Choosing an inkjet printer
Very often you come across the question: “I want an inkjet printer. Which one to choose?”. I will try to help in this choice. I’ll say a few things right away:
- I do not live in Yaroslavl, so the sources of information and information about the prevalence of certain models bear the imprint of my hometown. Some new models have simply not reached us yet, others have not received distribution. (Therefore, I ask you not to be offended by Lexmark fans. in Yaroslavl they are simply practically not sold. over, it is difficult to find consumables for them, so despite their outstanding characteristics, I will refrain from buying such a printer for myself. and many of my colleagues.) A separate article by another author is devoted to these printers.
- You cannot embrace the immensity! Recently, the number of models of inkjet printers has reached such a value that I just physically could not get to know all of them. Therefore, I will consider claims on the range of models considered quite fair, but useless 🙂 I am not trying to consider all the inkjet models available on the market, but I will limit myself to a number of the most common models that fit into the SOHO class (small and home office).
- Everything that does not concern technical data, the essence of my subjective opinion. Therefore, I foresee the expression of disagreement on certain points.
- I did not rate printers in terms of “noise”. I do not consider it to be a critical characteristic. over, when compared with the matrix, any inkjet “pleases the ear” (I’m not talking about the look) :-).
This is the fifth edition of this article. Since the moment it was first written, the situation on the inkjet market has changed dramatically. The list of printers is significantly outdated. However, I do not exclude obsolete models from consideration. They are still on sale, both used and, sometimes, new (if you’re lucky). This article, at one time, caused a huge amount of responses, which are presented in the comments. However, I do not agree with everything said in them, since they, in one way or another, reflect the subjective opinion of the author. Fixed some inaccuracies and added new information.
With a huge variety of offered models and brands, it is not difficult to make a mistake in choosing, and an unsuccessful purchase, most likely, will not be possible to return (exchange) or this will result in significant additional costs. Therefore, first of all, it is necessary to decide for what purposes the printer will be used. Whether you are looking for fast and inexpensive black and white printing, or are you going to take up digital photography and are willing to spend a lot of money on it. Do not forget about the cost of consumables. After all, an inkjet. the pleasure is quite expensive. Optimal use of an inkjet printer if you will be printing 1,000-5,000 pages per year. With smaller print volumes, you can, at one point, find out that the heads are dry and need to be replaced. For some brands this is not a tragedy, for others it is half the price of a printer. For large volumes of printing, consider whether you should buy a laser or LED printer, because the cost of consumables will be prohibitive. By the way, most printer manufacturers require the cartridge to be used up within six months after opening.!
The most common inkjets of four brands:
- Epson Stylus
- Canon Bubble Jet
- Hewlett Packard Desk Jet
- Lexmark color jet
Printers differ in both printing technology and command system. All Stylus use piezoelectric printing technology, resulting in significantly higher print quality at comparable resolutions. Since their cartridge is only a plastic can of ink, branded consumables are much cheaper. If you need to print in graphic mode from DOS programs, such as Lexicon, ChiWriter, Xerox Ventura Publisher 2.0, etc., then most Epson printers are able to understand the ESC P / 2 (Epson LQ) command system. with the exception of some models with the Photo prefix. and there are no problems with them in such cases. However, the shortcomings of the Stylus are a direct continuation of their merits.
The piezo head is a very expensive thing and requires delicate handling (however, it is enough to strictly follow the instructions). However, as experience shows, the use of non-original consumables is not so disastrous for her. The exception is counterfeit cartridges. here the head failure is almost 100 percent. And they get to the market in large quantities. However, Honor follows that there are some special rules that must be followed when refueling (here it is worth consulting with a person with similar experience). If you are not confident in your abilities, it is better to contact a company that specializes in refueling or purchase a non-original cartridge. Among third-party cartridges, I prefer BASF and that’s why: it is a fairly reputable company with its own chemical production and its own research laboratories. This means that you can be fairly confident that they are made with a sufficiently high quality and the technological cycle is observed at all stages. If the cartridge is produced by Ink Jet Something corp. it is very likely that the analysis of this ink was done by one company, the technology was developed by another, the ink itself is produced at the enterprises of a third, and the Ink Jet company itself is Something Corp. registered in Odessa on Malaya Arnautskaya :). And there are no quality guarantees here. Therefore, if you come across a cartridge of a manufacturer unknown to you, it makes sense to ask competent people whether it is worth contacting him.
It is highly not recommended for an Epson head for a long (more than 1 minute) removal of the cartridge. the ink dries up in the supply channels. Therefore, I would recommend that you first unpack a new cartridge, tear off all the appropriate stickers and, only then, press the cartridge replacement button. DO NOT ATTEMPT TO RINSE EPSON HEADS WITH ALCOHOL yourself. Alcohol destroys the coating of the nozzles and they become clogged more and more often. The ending is obvious. In the conference on this site, there were recommendations to soak the head in distilled water (in no case in boiled or from the tap. nozzles are oxidized by salts dissolved in water, etc.). You can add no more than 5% ammonia to it. In addition, an additional consumption of ink occurs each time the printer is turned on, when the printer performs the cleaning (or refilling) nozzles procedure for about a minute. And there is also a special mode for complete cleaning of the heads, (called by pressing a certain combination of buttons or from the driver), in which a significant drop flies out. By the way, there is a definite plus from the use of non-original consumables: the fact is that Epson branded inks are not just quick-drying, they are SUPER FAST DRYING, therefore, after a long downtime, a lot of ink flies out during the cleaning process. This happens much less often with non-original ink. Turning off these printers during printing is also dangerous for the heads. at an unparked head, the nozzles are open and can dry out. If this happens, then you need to turn on the printer again as soon as possible and perform a cleaning cycle or print something.
I consider myself obliged to dispel another “creepy” legend about Epson-ah: there is an opinion that a printer idle for 1 (2,3,4.) Weeks leads to inevitable drying of the heads. In fact, monthly (and even more) downtime for them is not a particular problem. But on one condition: the head must be parked. Parking does not take place immediately after printing stops, but, approximately within 10 seconds after that, with a characteristic click. On models with the “Pause” button, pressing it leads to immediate parking. Then the printer can be turned off.
So, to summarize: Epson is a ONE HAND MACHINE, moderately capricious, but providing the best quality in its class (especially on special grades of paper). Additional information about Epson-s can be found on the Russian official website of Epson and in one of the articles on this site.
Canon and HP printers have thermal ink heads that are replaceable with the cartridge or have replaceable ink tanks. This makes them more attractive in terms of refueling.
Canon is arguably the most user-friendly system for home use. The quality of black and white printing is comparable to HP, in color it is only slightly inferior to Epson and clearly surpasses HP (naturally in its class). You can hardly imagine an inkjet that is more optimized for refueling than Canon. The ink is held in the cartridge by foam rubber, which does not put forward special requirements for the tightness of the cartridge. They are very compact, which is important for the home. Most of the models understand the EpsonLQ and IBM XL command system. By the way, they use colored ink very economically.
The disadvantages of Canon include a small volume of black cartridges (although an increasing number of models can be supplemented with “big black” and successfully compete in this parameter with Epson and HP) and relatively low print speed in younger models. Currently, there are models that have a very high print speed. up to 10 ppm. (Canon BJC-5100) but they are quite expensive. Sometimes the lack of an output tray, sacrificed for compactness, is also recognized for the lack of a number of models. But, in my opinion, with infrequent printing, you can always free up space on the table for the output paper. In my opinion, this is the best option for home use, meeting most of the requirements for print quality. According to the instructions, the minimum paper weight. 65 g / sq.m. Maximum. some models take cardboard with a density of half a kilo per square meter :). The paper feed mechanism is not much different from the Epsonian and is just as reliable.
HP Desk Jet printers have arguably the fastest print speeds. They have established themselves as very reliable and easy-to-use devices. Such machines pay off rather in small offices, but not at home. The original paper loading system. from the front, from bottom to top, with a strong fold of the sheet, is hardly an advantage. With all the convenience of this system. the entire working area is in front, the printer can be “squeezed” into a space limited in height. it is very likely that several sheets will be captured at once. On a pack of 50 sheets, there will be a double grip 2-4 times. This mechanism seems to me not fully worked out. over, even when using high quality (80 g / sq.m) paper, you are not insured against this. For printing on special materials or on thin paper on older series printers, it was possible to feed them on a piece of paper from the back through a special slot window. Modern models of this window are deprived. True, the craftsmen manage to debug the mechanics of these printers so that he even takes a newspaper one. But this is not an option. not all are such craftsmen, and the guarantee is not worth the risk.
HP ColorJet Pro M479fdw Color Laser Multi-function Printer Review
For such a mechanism, it would not hurt to be able to “misplace” the paper path in order to pull out the jammed sheet with minimal effort. Unfortunately, in my experience, after a jam, the paper has to be pulled out piece by piece and, at times, tweezers have to be used. over, it is required to make “incomplete disassembly” by removing several covers and other assemblies. As it seems to me, a straight paper path like Canon / Epson. still preferable. According to the instructions, the permissible density of the paper used is 80–120 g / m2, ie. paper requirements are higher than Epson’s.
Refilling cartridges is a very delicate and “messy” multi-step procedure. It is impossible not to get your fingers dirty, even when acting with all possible accuracy. True, the significant volume of the cartridge allows you to resort to it not so often. in the economy mode it is possible to print 800-900 sheets of text, in the normal mode. half as much. The proprietary ink is highly water resistant. In general, the design of HP DJ cartridges is capricious. They place high demands on tightness, and the slightest crack makes the cartridge unusable.
These printers differ in the PCL command system, which is not critical in Windows, however, for DOS programs I managed to find drivers for them only in the Lexicon (version 1.3 and older). Although laser printers also use a similar command system, they use PCL-5, and in inkjet systems PCL-3, it is not always possible to slip a laser driver into them.
One more point regarding print quality. It occurred to me to examine the results of printing a number of printers under a microscope and this is what happened:
- Epson Stilus color IIs. neat round dots.
- HP DJ 400. spits, strokes, etc.
- Canon BJC-250. similar to the previous one.
- Canon BJC-2000. slightly less neat than color IIs round dots of two sizes are large, and between them are small.
I cannot fail to note one more point: a couple of years ago, almost all low-end inkjet printers were able to print in color only by replacing the black head with a 3-color one and, accordingly, were significantly inferior to their older brothers in print quality. Currently, it is in this field that the most serious changes have taken place. Almost everyone, even the cheapest inkjets, have acquired the ability to print in full color, at least by using a special cartridge. The trend, however 🙂
Now let’s try to “disassemble” individual models. I conventionally divide them into 3 classes, based on price and capabilities. However, Epson currently produces models that occupy an intermediate position, at least in terms of price. So:
Middle class: Epson Stylus Color 400, 640, 660, HP DJ-670c (690s), Canon BJC-4300 (120-150)
Among the new models in this class, Epson again offers us a “sweet couple” Stylus color 640/660. They differ from each other in the same way as the Stylus color 440/460. The resolution of these models is 1440×720. Speed up to 6 ppm. in b / w and up to 4 in color. I would consider these printers to replace the out of production Stylus color 600, if not for the reduced cartridge resource. 370 pages.
Status. In production.
The HP DJ-670c and 690c are very fast and high quality small office units. There is a photo cartridge for the 690. However, applying it on plain paper is unlikely to generate a sense of satisfaction. A distinctive feature of this pair is a mechanism that excludes smearing of the wet image on the previous one by the emerging sheet. The sheet crawls out onto special guides and, only after that, is thrown into the receiving tray. Otherwise, all characteristics are quite average. The optimal solution for a small office. Very “foolish”.
Status-Out of production
670th, under certain conditions (for example, when there is little ink in the cartridge), sometimes it also “streaks” the solid fill. One of the disadvantages of these devices, I would consider the lack of a button for replacing the cartridge (or rather, its combination with the front cover). As a result, when the cover is opened, the printer stops printing and moves the cartridges to the central position for replacement. Therefore, if the leading edge of the paper is jammed when exiting the printer, you cannot open the cover and continue printing. The previous model, 400, does not have this problem. Of course, they might object to me something like: “Only print on good paper.” Alas, the realities of life are always far from ideal. I have to feed my DJ-400 what they give (mostly newspaper and some white writing), and not what I want. And I’m not very sure about my uniqueness 🙂
Status-Out of production
HP DJ-710. a significant jump in the quality of the resulting print. the manufacturer positions itself as a printer with photo printing capability, but 600 dpi resolution, in my opinion, is not enough for this. Has retained all the advantages of previous models. Unfortunately, my acquaintance with him is very limited. I saw a picture (not a photograph, but a drawing with text) printed on good office paper. great. For all my dislike for HP, I can’t help but give them credit.
Status. In production.
Canon BJC-4300 is a very original multifunctional device. It is distinguished by a large range of cartridges. Here there is a “big” black, and a block of black and color, and a photo cartridge, and also a cartridge with fluorescent “neon” ink. However, “neon” printing does not strike the imagination, except from the point of view of advertising. By the way, according to some sources. I have not seen it myself. the “neon” cartridge exists for the previous model. over, the four-color block for color printing can be replaced as a whole (in case of failure of the heads) and only the ink tanks. By the way, the ink tanks for each color can be changed independently. The “large” black ink cartridge. especially for office printing. replaces the 4-color block and prints much faster with it. This cartridge is one-piece and can (and should) be refilled. An interesting feature of this device is the ability to replace the printing unit with a special scanning module, which turns it into an original sheet-fed scanner. However, for the same money, you can now buy a cheap tablet with similar characteristics. So, what is it worth, is the skin of the dressing. And the quality, according to some reports, is not ah. I also note that this printer has “older brothers”, which differ from it mainly in the width of the carriage. BJC-4550/4650. A3 format and BJC-5500. already A2 format! BJC-4300 resolution. 720×360.
Status-Out of production
Canon BJC-5100 is a new model in this class. This printer is focused on the speed of 10 ppm. in my opinion it is a record for an inkjet printer of this category. As for the permission. The standard print head BC-21e known to us from the 2000th model provides 720×360 in b / w and 360×360 in color. There is also a “big black” cartridge, but its own. ВС-23. This printer can be considered a very serious office model.
Status. In production.
Lower class: Epson Stylus (color) 200 and color 300, HP DJ-400, DJ-420, DJ-610, Canon BJC-250, BJC-1000, BJC-2000 (up to 100)
The Epson Stylus color 300 solves this problem in an original way. it is 4-color, but has a single cartridge for all 4 colors. As a result, with intensive text printing, color ink will be lost and vice versa. This idea does not seem justified to me. The previous model is Epson Stylus 200. It seems to me a more successful solution. It has, in my opinion, the largest black cartridge of all the Epson inkjet family. By the way, I was more than satisfied with the results of its printing.
In terms of quality and capabilities, both Epson models are approximately identical. The print quality is such that when using special paper, the image is close to photographic. Maximum resolution 360×360 dpi in 720×720 matrix (this means that the dots are printed in a checkerboard pattern).
Status. Both models are discontinued
The HP DJ-400 is the cheapest of the four. But, in terms of print quality, it is only suitable for text and outline images (where it gives very good results). But when displaying pictures with a solid pattern, stripes are clearly visible. This is due to the peculiarity of the formation of the picture in the highest quality mode. The fact is that printers of other brands form an image in 3 (or more) passes with a shift of one third (or more) lines. In this case, each line is sprayed, as it were, in 3 (or more) layers. The DJ-400 is limited to two layer passes in half-line increments. Printing in color is just gross. Resolution 600×300.
Status-Out of production.
The HP DJ-420 is a minor modification of the previous model. In my opinion, the changes only affected the design of the case and the elimination of the DOS firmware. Has proven itself even worse than the “four hundredth”. paper loading was extremely unstable. In one of the computer firms he was described to me as a “paper gnaw”.
Status. Presumably out of production.
The HP DJ-610 is a new low-end model. In appearance and device it resembles the HP DJ-670/690, which it approaches in quality and print speed. It looks like the paper loading mechanics have been seriously improved. the samples I know loaded 65 gsm sheets with quite acceptable reliability. A very interesting feature of this printer is the reduced cartridge life. And this does not mean that its size has decreased. It’s just that there is an obvious underfilling (20 ml versus 40 for the DJ-400/420). When refueling, you can safely fill the cartridge “under the cork”. Allows the use of a photo cartridge (I have never seen the results and I do not presume to judge). Resolution 600×600.
Status. In production.
Canon BJC-250 when printing text on ordinary office paper differs little in quality from DJ-400. When printing with an ordinary color cartridge (there is also a photo cartridge for it), the picture printed with a resolution of 360×360 practically does not differ from that obtained by the Epson Stylus 200 at the same resolution. The maximum resolution is 720×360. By the way, in my opinion, it would be more correct to call a photo cartridge a cartridge for high-quality printing. after all, it is difficult to talk about photo printing at this level. At the same time, working with the use of a photo cartridge, Canon BJC-250 in full color mode can compete in quality with more advanced HP DJ-6xx series. The only inkjet of this class at the moment that has full Russian support for DOS, however, there have been deliveries to Russia of large quantities with Western European firmware. The cheapest solution, taking into account non-original consumables.
Status. In production.
Canon BJC-1000 differs from the previous design and slightly increased speed. A purely Windows-oriented printer. Canon raster command system. The nomenclature of cartridges and other characteristics are the same.
Status. In production.
Canon BJC-2000 is a very original and balanced solution. In fact, this is a somewhat lightweight Canon BJC-4300. It is indistinguishable from Canon BJC-1000 in design, but significantly surpasses it in capabilities. Also only works under Windows. Standardly completed with a head with replaceable ink tanks (separately black, separately 3-color) ВС-21е. The service life of the head starts from 3000 pages (subject to certain accuracy and 5000 is not the limit), a little more than 200 ink tanks. For large volumes of b / w printing, it is worth using the 900-page VS-20, which has a non-replaceable ink bottle. It can be refueled up to 10 times. The use of this cartridge increases the printing speed. The list of cartridges for this printer also includes a 4-color photo cartridge (BC-22e), a fluorescent cartridge (BC-29F) and a scanning module (IS-22). The difference between the Canon BJC-2000 and its peers is the Drop Modulation technology, which allows you to control the point size. It is more accurate to spray dots of two sizes. large and small. The photo cartridge allows you to get a much finer raster than the standard head. You should be very careful when buying a head for this printer. The fact is that the BC-21e head for the BJC-2000 is not interchangeable with the BC-21 used in the BJC-4×00 printers (but on the contrary. installing the BC-21e on the BJC-4×00 is allowed) and this can damage the printer. 360×360 resolution with standard head.
Officially, BJC-1000/2000 printers are not intended for printing from DOS, however, by installing a certain resident driver, you can quite comfortably print in graphic mode from programs that support the ESC P / 2 (Epson LQ) command system. You can download this program from here. It allows you to print from Lexicon, ChiWriter, Grapher, and much more. Suitable for BJC-1000/2000/6000/7000 printers, supposed to be suitable for BJC-5100 and others controlled by Canon raster command system.
Status. In production.
An intermediate place between this and the next class is occupied by Epson Stylus Color 440 and 460
I have singled out these printers into a separate group mainly because of their price. 115–120, which is slightly more than the above models. The difference between these models lies in the print head. Stylus Color 460 has the ability to control the size of the applied point. Print speeds: Epson Stylus Color 440 gives 4 ppm in bw and 3 in color, and 460 is 4 and 2.5, respectively. These are full color printers. Otherwise, these are very similar models, having the same consumables, technical characteristics and almost indistinguishable in appearance. Finally, Epson honestly wrote that the cartridge resource is 370 pages. According to the manufacturer, they support the ESC P / 2 (Epson LQ) command system. Resolution 720×720 dpi.
Status. In production.
Higher-end printers are now found not only among Epson Stylus Color, but also among all other manufacturers. These are the HP DeskJet-815 and 970Cxi and Canon BJC-7000. There is also information in this category for the Lexmark 5000 (150)
Printers Epson Stylus color models 600, 800 and 700 with a resolution above 720 dpi: Epson Stylus 600 and 700. 1440х720, Epson Stylus 800. 1440х1440. Images printed at this resolution on special paper look very realistic. The grain in the photographs is noticeable only from a close distance, and even then with very careful examination. By the way, the issue with 800 resolution is very interesting. The fact is that it has a head twice as high as the 600th (128 nozzles versus 64 in b / w and 64×3 versus 32×3 in color). Therefore, in the literature and even on the official website of Epson, the resolution is 1440×1440 or just 1440 dpi. But in the documentation that comes with the printer, only 1440×720 is listed. At the same time, 1440×1440 is also present in the driver. Generally. 🙁 In terms of ink consumption (black) Epson Stylus 600 should be recognized as very economical: a brand new Epson 600 with “native” ink tanks finishes the second 500-sheet ream of paper. Print mode. 40-45 percent normal, 55-60 economical, Times New font Roman Cyr 14. And about a quarter of the ink still remains.
Status. Both models are discontinued
A pair of Epson Stylus color 740/760 are the new multi-purpose office models. 1440×720 dpi. 6 ppm both in b / w and in color are quite impressive. The very solid. as much as 900 pages. black cartridge makes them very attractive for a wide range of applications. A pleasant surprise awaits us in the 740th model. FULL DOS support, including a solid set of built-in fonts.
Status. In production.
The Epson Stylus photo 700 has the prefix photo in its name, which indicates that it has been optimized specifically for these tasks. It’s not just a color inkjet. The 5-color color cartridge makes it stand out from the crowd. I saw the results of his work. amazing! However, this quality is achieved only on expensive special paper. To use it for printing text, in my opinion, is an unnecessary luxury. A person who is able to afford such an “expensive toy” will quickly come to the conclusion that it is not a bad idea to put something simple like a DJ-400 or BJC-250 next to each other and produce pieces of paper on them 🙂
Status-Out of production
The Epson Stylus photo 750 is the next step in Epson’s line of photo printers. Here again we find a head capable of delivering drops of different sizes. Naturally 6-color printing. On photographs printed on special paper, the raster is not visible to the naked eye. Great photo printer.
Status. In production.
The HP DJ-815 is a solid high-speed office machine. A very nice feature of this printer is DOS support, with a good set of fonts, which will allow it to be used in accounting or in a warehouse. There are plenty of Dos programs for this purpose. It can be completed with a black cartridge with an increased amount of ink, which is important for office tasks. Quite decent print speed. up to 7.5 ppm. The resolution is traditional for HP. 600×600.
Status. In production.
The HP DJ-970Cxi is a promising model with very serious photo printing capabilities. Has real, albeit slightly limited, DOS support. The print quality looks just great, the b / w print is not inferior to the laser one. Print speed is also great. up to 12 ppm. The resolution declared by the manufacturer is 2400×1200 dpi. Naturally, it can only be realized on special paper.

Canon BJC-7000 is a new device that really has a reason to relate to photo printers. 7-color printing. This printer uses an original paper preparation system for printing. Before spraying the actual ink, a special optimizer is applied to the paper, which creates a kind of coating and improves the print quality. According to the manufacturer, this eliminates the need for special photographic paper. This seems somewhat dubious to me, but the prints I have seen look very dignified.

Epson Inkjet vs Laser Printer Street Challenge
The Lexmark 5000 is the only printer of this brand that I have been able to obtain information on. Judging by the characteristics, it is a very decent device. Judge for yourself: full-color two-cartridge, resolution up to 1200×600 in b / w and color, there is a 6-color photo cartridge. The price is comparable to the printers of the previous class (but, like all inkjets of this brand, expensive consumables). There are drivers for Windows 3.x, 95, NT, prints from DOS. This seemed to me pretty.
So, to sum up, what, after all, to choose. The answer to this question should be the requirements for the print quality and the price of consumables (including non-branded ones). Obviously, the desire to print photos with very high quality will force you to stop at the older Epson Stylus models. And saving on consumables is inappropriate here. If the printer will work in a small office and its main products will be text documents and, occasionally, graphics are not photo-quality, and the print speed is quite critical, then various models of Hewlett Packard Desk Jet of the lower and middle level justify themselves here. At the same time, refilled cartridges can be used for printing drafts and turnover, and for especially important and ceremonial documents, you can keep a branded set (which is what I actually do at work).
For home use, especially in the case of limited financial resources, when printing speed is not particularly important, but the ability and convenience of refueling is critical, the various Canon BJC models come to the fore. In my opinion, this is the optimal solution for most home printing tasks.
All information about the described modeling is gleaned from both personal experience, and from the experience of my friends and acquaintances. I would be grateful if anyone could add information about other brands of inkjet printers (especially Lexmark and Samsung) to this essay. Without pretending to be infallible, I will also be grateful to everyone who considers it necessary to correct me.
P.S. And, lastly, a small surprise: I bring to your attention some original recipes for homemade ink for printers with thermal ink heads.
1) The recipe was developed at the Institute of Microelectronics and Informatics of the Russian Academy of Sciences for the Canon BJ 300 printer, where it became widespread. The main component is black chrome dye used in the production of felt boots and tarpaulin boots. Of course, not the most affordable chemical, but if you want, you can get it. The dye is dissolved in distilled water until it is completely saturated (ie, dissolved in water heated to 60-70 degrees “until it stops” and allowed to cool). Then add glycerin. Unfortunately, the proportion of glycerin can only be specified for Canon BJ 300 printers with a resolution of 300 dpi. 40%. Glycerin is added to increase the viscosity of the ink. Obviously, its proportion will have to be selected empirically. Before use, the composition is recommended to be thoroughly filtered.
2) The composition used by a friend of mine for Canon BJC-250 (again Canon). 40% isopropyl alcohol, 40% medical glycerin and 20% dye. As the latter, any liquid, water- and alcohol-soluble dye is suitable, for example, foreign-made ink. You can also use domestic ones, but only after thorough filtration. The cartridge can withstand at least 10 refills with such ink.
Features of the inkjet printer
- The printing principle is inkjet. Ink is fed through special nozzles and printed on the canvas. Unlike needle printers, where the application of ink is a shock-mechanical process, inkjet is very quiet. You cannot hear how the printer is printing, you can only discern the noise of the engine, which moves the printheads. Noise level does not exceed 40 dB.
- The print speed of an inkjet printer is significantly higher than that of a needle printer. The print quality also depends on this indicator. Principle of printer printing: the higher the speed, the worse the print. If you choose a high quality print, the process slows down and the ink is applied more carefully. The average print speed of such a printer is approximately 3-5 pages per minute. modern models have increased this figure to 9 pages per minute. Color printing takes a little longer.
- Font. this is one of the main advantages of an inkjet printer. The font display quality can only be compared with a laser printer. You can improve print quality by using good paper. It should be fast-absorbing. A good image is obtained on paper with a density of 60-135 g / m². Copier paper with a density of 80 g / m² also performed well. To quickly dry the ink, use the paper heating function. Despite the fact that the principle of printing inkjet and laser printers are completely different, high-quality equipment allows you to achieve a similar effect.
- Paper. Unfortunately, the inkjet printer is not suitable for printing on roll media. And to get multiple copies, you will have to use multiple printing.
How does a laser printer print?
Principle of laser printer printing in brief:
- The laser printer applies the image to the canvas in several stages. Toner (special powder) melts and sticks to paper under the influence of temperature.
- A squeegee (special scraper) removes unused toner from the drum into a waste accumulator.
- The caronator polarizes the surface of the drum and, by means of electrostatic forces, assigns a positive or negative charge to it.
- The image is formed on the surface of the drum using a rotating mirror, which directs it to the desired location.
- The drum moves along the surface of the magnetic roller. The shaft contains toner, which sticks to areas of the drum where there is no charge.
- The drum is then rolled over the paper, leaving the toner on the web.
- At the final stage, paper with toner sprayed on it is rolled through an oven, where the substance melts under the influence of high temperatures and reliably adheres to the paper.
The printing principle of a laser printer has a lot in common with the technology used in copiers.
How ink is stored and applied to paper
gas bubble method;
The first method, when printing, leaves an ink point on the canvas, due to the piezoelectric element. It shrinks and expands the tube, preventing excess ink from getting onto the paper.
Gas bubbles, also known as injection bubbles, leave an imprint on the canvas due to high temperatures. Each nozzle of the print matrix is equipped with a heating element that heats up in a fraction of a second. The resulting gas bubbles are pushed through the nozzle and transferred to the consumable.
The drop-on-demand method also uses bubbles during operation. But it is a more streamlined technology that dramatically increases the speed and quality of modern printing.
An inkjet printer stores ink in two ways. There is a separate removable reservoir from which ink is supplied to the print head. The second way to store ink uses a special cartridge, which is also located in the print head. To replace the cartridge, the head itself must be replaced.
What’s the printing principle of inkjet and laser printer? How an inkjet printer prints
It’s hard to imagine modern life without a printer. Scripts are printed at schools, abstracts at university, contracts at work, and even at home, it is extremely necessary for us to transfer this or that information to paper. There are several types of printers, they are classified by the type of printing, by the format, by the size and even by the type of printed matter. Consider the principle of printing an inkjet and laser printer.
Let’s talk about inkjet printers
Initially, a three-color set was offered, which included all of the above tones, except for the black shade. But when overlaying yellow, cyan and magenta, at 100% saturation, it was not possible to achieve black. As a result, a brown or gray color was obtained. Therefore, it was decided to add black ink.
Color laser printers and their main differences
Printing on a color printer consists of the following steps: analysis of the image, its bitmap, the arrangement of colors and the corresponding toners. Then the charge distribution is formed. After the procedure is the same as for black and white printing. The ink sheet passes through the oven where the toner melts and adheres securely to the paper.
Their advantage lies in the fact that the principle of printing a laser printer allows you to achieve very thin beams that discharge the desired areas. As a result, we get a very high-quality high-resolution image.
Advantages of Inkjet Printing
- Attractive price, ideal price-performance ratio.
- The printer has very modest dimensions, which allows it to be placed in a small office, without creating inconveniences for the user.
- Cartridges are easy to refill by yourself, just purchase ink and a guide.
- Possibility of connecting a continuous ink supply system. With large volumes of printing, this will significantly reduce costs.
- High quality photo printing.
- Wide range of print media.
Construction of laser devices
Laser printers succeed in obtaining high-quality printing due to technological features. They include the following elements.
- The drum is an aluminum cylinder. It is treated with a light-sensitive material that tends to change its electrical resistance in the presence of light.
- A magnetic roller is used to transfer toner from the reservoir directly to the drum or developing roller found in some modern printers.
- The squeegee knife acts as a cleaning blade. With its help, the excess dye is removed from the raster roller. It can be made of plastic, steel or fiberglass.
- Waste toner hopper is made in the form of a container. This compartment can be located separately from the cartridge or with it. The filling speed of such a reservoir depends on the quality of the toner.
- The laser unit is designed to create an invisible image on the surface of the drum by illuminating specific areas. Beam intensity can vary significantly.
- The primary charge roller is made in the form of a metal rod covered with a rubber layer. This element allows you to ensure the uniformity of the negative charge.
- Transfer belt is required for applying intermediate results with color cartridges.
- The development unit allows toner to be transferred directly onto the electrostatic image created on the surface of the photoconductive element.
Basic inkjet technologies
- The piezoelectric method involves the formation of ink dots on paper using special devices that have a connection with the diaphragm. The electric field has a direct effect on the piezoelectric element, and it expands the tube to fill the capillary system. The main advantage lies in the flexible control of the droplet size, which makes it possible to obtain high-quality images with high resolution.
- The bubble method involves heating elements directly in the nozzles. An electric current is passed through them. In the process of heating, gas bubbles are formed, which push the required portion of liquid ink through the holes. After the heater has cooled down, a fresh portion of the coloring matter enters through the nozzles. High quality is noted with detailed line drawing, but when printing solid areas, there may be slightly blurry spots.
- The thermojet method, as in the previous case, involves the use of a heating element. However, together with it, a special mechanism is used that allows for a faster injection of dyes. In this regard, the performance of the devices increases. The color palette of the resulting image is distinguished by contrast.
The ink used can have a different composition. Water-based ink contains a soluble dye and certain additives to adjust the viscosity. Their advantage lies in their low cost. Pigment ink is UV and humid resistant. The print quality in this case is less dependent on the media.
Using continuous ink supply
With the principle of printing an inkjet printer, everything became clear. Special cartridges are used to store the dyes. However, there is a special system that allows you to provide continuous ink supply in order to save. In this case, the capsule tanks are installed directly on the printhead.
The system is a set of containers connected by a silicone loop through which ink is supplied from donors to the main unit. Thanks to such a device, a constant presence of the original dyes in the print head is achieved. Many large format office appliances have a built-in ink delivery system that cannot be seen from the outside.
How the laser device works
A completely different branch of the development of printing devices is laser technology, with the help of which it is possible to achieve high-quality application of dyes on paper. The formation of symbols and images occurs due to the illumination of the beam of the elements of the device with photosensitivity. The resulting copies with text or graphic information are resistant to fading and abrasion.
Inkjet and laser printers have completely different printing principles. The colorants are toners, which can be transferred to solid media in three ways.
- Using a two-component development system. The dye particles required for transfer to a special photosensitive drum cannot be fixed on a magnetic shaft without a special magnetic carrier charged by stirring.
- With the use of one-component toner without additional additives. Particles of matter in this case are endowed with magnetic properties. Some devices may carry out electrostatic deposition. With this option, the toner does not require magnetization.
- Using a factory blended two-component dye.
Unlike an inkjet printer, the principle of printing a laser analogue is based on the construction of an image using a photographic method. The laser beam hits a special shaft, the surface of which is electrified due to impact ionization of the internal air.
Working principle of inkjet printing device
Still, it is an inkjet printer that is most often used at home. The principle of its printing is to form an image using liquid ink. They are transferred to the media through special nozzles located on the head. The number of these holes depends on the printer model. Usually their number ranges from 16-64 pieces.
Since the principle of printing an inkjet printer assumes the use of liquid ink, with prolonged inactivity, they dry on the nozzles of the head. This requires cleaning the printing element, which implies additional consumption of dyes.
Such devices consist of the following components:
- supporting structure;
- power supply unit;
- print head;
- purification system;
- media feeding devices;
- control unit.
A color image is obtained by superimposing three basic colors on top of each other. Black ink is often added to them so that it is possible to use devices for conventional printing of texts and black-and-white drawings, saving on color inks.
Laser printing process
Not everyone fully understands the principle of printing laser printers from computer science courses. Inkjet devices work according to a simplified scheme, so there are no special questions about them. How does the laser printing process take place??
- The photoconductive roller is charged first. An electric charge is evenly distributed over its surface by rotating the roller. Rotating rod system reduces stress and reduces ozone emissions.
- Laser scanning is in progress. At this moment, the charged surface of the shaft passes under the light beam. The laser hits only those places where the dye will be applied in the future.
- Toner is being applied. The roller, which has a negative charge, transfers it to the toner. The dye from the hopper is attracted directly to the magnetic shaft, after which it comes into contact with the photoconductive element in those areas where a negative charge remains.
- The transfer roller, which is in contact with the solid carrier, is no longer negatively charged, but a positive one. Particles of the coloring matter fall on the surface of the paper due to electrostatic action.
- The toner dispersed throughout the media is cured by heat and applied pressure. The thermal chamber consists of two shafts between which the paper moves. The temperature is controlled by a special sensor. The colorant is melted and embedded in the texture of the paper.
Laser and inkjet printer: printing principle
In everyday life, laser and inkjet printers are popular. The principle of printing such devices is fundamentally different, which cannot but affect the operational features. In some cases, it is best to use laser products, while in others, inkjet products. However, it is possible to make the final choice in favor of this or that device only after considering the operation scheme.
It is suggested to take a look at the table to compare the properties of inkjet and laser printers, the printing principle of which is very different.
