Why The Laptop Does Not See The Printer Through The Cord

Mechanical problems

The first thing to consider is the SIMplest option: try unplugging the cord and plugging it back in. Next, make sure that the plug is firmly inserted (until it clicks), check the wire for mechanical damage and make sure there is a signal in the cable itself. It would be ideal to insert the cord into another computer, if there is no such problem on it, then the matter is in the laptop.

Why The Laptop Does Not See The Printer Through The Cord

Inspect the contacts and the connection between the wires and the plastic plug; if a break is found, the cable should be replaced. It is cheap, but the replacement procedure itself may require the help of a professional if you need to pull the wire through the wall. Sometimes it helps to rewind the contacts with electrical tape, but this mayor will not provide reliable durable connections.

The laptop does not see the network cable (internet cord). Reasons and what to do. Repair in St. Petersburg

Let’s figure out the reason why the laptop does not see the network cable (Ethernet cable of the Internet) and try to fix the problem ourselves.

Despite the widespread use of Wi-Fi, a wired network connection is still the easiest, most stable and reliable one. The network cards of modern laptops are almost always supplied with preinstalled drivers, which means that most often, to connect to the Internet, you just need to plug the cable into the desired port. In practice, laptops sometimes refuse to recognize the wire, such a failure can occur for various reasons.

Drivers

If the physical damage has been repaired, and the laptop still cannot see the network, you should pay attention to the drivers. On modern operating systems such as Windows 7 and 8, reinstalling THESE software components is easy.

  • You need to press the WindowsR key combination, write devmgmt.Msc in the console that appears and press “Enter”.
  • This will open a list of all available devices, where you can find installed network cards in the “Network adapters” category. Usually their names contain the name of the manufacturer’s brand, for example, Intel or Realtek.
  • I called the right button on the device, you need to click the “Delete” button in the menu that opens.
  • When you reboot, the system itself will find the necessary drivers and install them.

For old laptops, it is important to install drivers from disks, which usually come in the kit, in some cases they can also be downloaded on the network. A green signal to the plug is a characteristic sign of network cable operation, although the presence of a glow does NOT guarantee that the cable is working correctly.

The absence of visible changes after all procedures usually means the failure of the controller or port. Repair or replacement of a network card in a laptop should be entrusted to a specialist.

If the problem of detecting a mobile device by the computer has not yet been resolved, reset the settings

If, until now, your computer does not see the phone via USB, it should help resetting the smartphone using Hard Reset. Go to the settings of your phone, select the “Backup” menu item, and in it select “Reset data”.

But I warn you right away that you will lose your files and settings located in the internal memory of the phone (files on the SD card will remain intact), so this item should be used only as a last resort!

The phone may NOT be detected by the computer due to viruses

It is trite, but all kinds of virus programs can block work with external mobile devices. Try to scan your computer with Dr. Web CureIt !, in some cases it can help.

So why does the computer not see the phone via USB, but is charging. hardware reasons

The USB cable is damaged. It often happens that the cause of this dysfunction is damage to the USB cable itself. Cables of little-known or “non-name” manufacturers do not have a large margin of safety, and may fail literally in a couple of months from the start of operation, and as a result, the computer will NOT detect the connected phone.

Check if the USB cable is damaged

In addition, even the most reliable cables from global brands are susceptible to stochastic damage. they can be accidentally damaged during use, can be chewed by pets or spoiled by children. After that, first of all, inspect your USB cable for the possibility of mechanical damage, and, if the external cable is intact, try using it to connect your device to a second computer. If the device is NOT recognized on another PC. try replacing the cable.

The USB port on the computer is damaged. The USB ports used in a computer are also susceptible to various mechanical damage, including damage to the USB controller as well as the south bridge of the motherboard. Try to insert the cable into a different USB connector, if this does not help to fix the connection of the phone to the PC, follow the further tips.

Check if the USB port on the computer is damaged

Damaged cable jack on the phone. Has water got into the socket of the smartphone and is it damaged? If yes, then it needs to be replaced.

Turn off the battery, Pull the battery out of it for a few seconds, then turn it back, and turn on your device back.

There are no drivers for the phone on the computer

Although, usually, a computer with the latest OS detects and sees a smartphone via USB without problems, the opposite can be observed. Try to search for a driver for your smartphone on the network, sometimes a driver may come up for SIMilar models of this brand.

Why the computer does not see the phone via USB, but is charging

Many users, when trying to connect a phone to a computer using a USB cable, are faced with the fact that the computer does NOT recognize the connected gadget. The connected device is charging, while there is no access to the smartphone itself and its internal content. I also encountered this synchronization problem, and in this material I will tell you why the computer does not see the phone via USB, and I will also share various methods for solving this issue.

Phones are connected via USB to computer

The computer does not see the phone via USB. software reasons

After describing the hardware reasons, we will list the main software reasons, if your computer still does not recognize the cell phone connected with the USB cable, follow the further instructions.

We work with the settings. We go into the settings of our device, select “Memory” there, click on the three dots at the top (Properties), select “USB connection to a computer” and put a tick in front of “Media device” (“USB drive”). If you have a checkmark opposite to use USB as a modem. Uncheck it.

USB connection settings to computer on Android

Windows Update (to download drivers for your phone) and New Device Discovery must be enabled on your PC. Remember to unlock your phone when connected to your computer, this is important.

If you are a conservative and have Windows XP, download the MTP (Media Transfer Protocol) for XP from the Microsoft website and install it on your computer.

If your USB.Ports drivers are missing, the computer may NOT see the phone. If the drivers for the USB ports are dysfunctional, the latter SIMply stop working. To fix this problem, install USB drivers from the “native” driver disk to your PC’s motherboard, or download the latest drivers from the motherboard manufacturer’s website.

Also, due to some reason, power may be turned off for a number of ports.

  • Go to the “Power” section (Control Panel. Hardware and Sound. Power Supply)
  • Select “Configure Power Plan” opposite the power plan you are using;
  • Then click on “Change advanced power settings”;
  • Find “USB Settings” in the list that appears, click on the plus sign opposite;
  • And then on the plus sign next to “Parameter for temporarily disabling the USB port”;
  • Change the setting to Disabled for both mains and battery power;
  • Click “Apply” and “Ok”.

Turn on USB ports

The device drivers have flown. Go to “Device Manager” and see if there is a question mark or exclamation mark in the “Portable Devices”.

Check if your device is there and make sure it is working properly by right clicking on it and clicking Properties. If it is there, or you have doubts, uninstall the driver, Disconnect the phone from the computer, and then turn it back on, and let the system install the driver again. This may help solve the problem that the smartphone does not connect via USB to the computer.

Installing device drivers

Also, it will not be superfluous to enter the website of the manufacturer of your smartphone and download the latest drivers for it on your PC (for example, for Samsung there is a special software Samsung Kies).

Install update KB3010081 (KB3099229). Windows 10 owners may need to install update KB3010081, which is responsible for working with Windows Media Player. This player is directly related to the normal operation of the MTP (Media Transfer Protocol) service, so download and install these updates.

Also, a common prerequisite may be an unreliable assembly of the OS itself on a PC. Only rearranging Windows to a more working version will help here.

Custom firmware is not working. The desire of many fans to play with the firmware for their Android device can do them a disservice in the form of the device’s failure to work normally with the computer. Try restoring to stock firmware or recovering from a backup (if available).

Reasons for not connecting your phone via USB

The whole complex of reasons for the problem that the NK does not see the smartphone through the USB cable, I would divide into hardware and software, and below I will list each of them, SIMultaneously providing instructions for its correction. But before using the methods I have indicated, try restarting your computer and smartphone. this does not help as rarely as it seems. This problem mainly occurs with devices from Samsung, Lenovo, HTC, LG and Fly.

The computer does not see the phone via USB, but it charges

As you can see, problems with the lack of visibility of the connected phone on the PC can be of both software and hardware nature, and there are a lot of such problematic factors. I would advise you to first pay attention to the probable mechanical damage in the cable and device, and only then switch to software methods.

In many cases, a SIMple restart of the smartphone (temporary removal of the battery), as well as working with the phone’s USB connection settings, can help. If all of the above does not help and the computer does not see the phone via USB, but is charging, then you may need to contact a qualified service center.

Why can NOT see laptop printer via usb? Understanding

Greetings, friends! Sometimes it happens that when you need to print something, the laptop does not see the printer via the USB connection. At the same time, it seems that everything is installed and connected correctly. There are several explanations for this and below I will talk about all possible situations.

Physical problems

So, if Windows 10 does not see the printer, then first of all you should check if it is turned on. Many printers have two buttons that supply power. One is located on the front and the other is often located at the back. Many users do not suspect it. It happens that someone turned off the power with the back button, and the new user did not take this into account. The included device has a light indication, it allows you to understand that the device is ready to work.

The second likely reason is a broken or disconnected USB cable. In the first case, the check is carried out by replacing the wire or connecting the second device with this cable. If the computer or printer has recently been moved, then it may SIMply be disconnected.

Another point that touches the wire is the first connection to the PC. If the device is installed for the first time, you must strictly follow the recommendations prescribed in the instructions. Many manufacturers indicate that the printer and PC should be connected at a specific point in time when the driver installation program requires it. It is incorrect to connect both devices to the unit. The printer must be disconnected from the power supply when connecting a wire to it. When the laptop says to turn on the printer, only then the power is supplied. Violation of THESE recommendations is the answer. why the computer does not see the printer.

Types of faults

There may be several breakdowns due to which Windows 10 does not see the printer:

  • The device is not included;
  • Faulty wire;
  • Missing or old drivers;
  • A different printing device is selected;
  • Virus;
  • Failure in the automatic operation of the print service;
  • Disconnected USB controller;
  • Physical breakdown.

The reasons why the laptop stopped seeing the connected printer are very different and most of them can be completely solved on their own, without resorting to the services of specialists. The only exception is physical damage, it is obvious that in this case, repairs will be required at a service center.

Programs with software

PC software is an essential part of any device. Without the presence of a driver or its incorrect operation, the device cannot be detected by the PC. An important point when installing the driver is to use the latest versions designed for a specific OS and Windows bit depth. Renowned manufacturers HP, Canon, Epson include a software disc in the kit. It should be understood that during the implementation of the device, the software may become outdated, as new versions of drivers appear. I recommend installing the program for the printer from the disk, and downloaded the current version from the manufacturer’s website. This will save you time and effort.

What to do if the printer has been in use for a long time and it suddenly stops working. I recommend checking the driver. It could have been damaged by a crash in the operating system or by a virus. First of all, you should install the Antivirus software and clean the system, then, if there are available restore points, roll the system back to return to the working version of the software. If this does not help, then the easiest option is to reinstall the drivers.

An OS failure often causes malfunctions in the printer itself of the laptop controllers used to connect. When connecting an MFP, a USB connection is used. For various reasons, controllers may stop working correctly. In this case, the laptop stops seeing the printer, flash drives, mouse and all devices connected via the USB input. You can check if the USB connectors are really to blame through the device manager. It displays all the nodes of the laptop, if any icon has an exclamation or question mark, then it does not work correctly. In this case, you will need to install a driver on it. This can be done directly through the properties (update the driver item) or previously downloaded it on the manufacturer’s website for a specific model.

Sometimes the printer is detected by the laptop, but it still does not print. This is possible if several printing devices are connected to it. The system always selects one of them by default. In this case, when sending documents for printing, the printer will perform the job by default. There are two ways out of the situation. to set the desired printer for automatic printing or to select it manually each time.

In order to become the main one, you need to do the following:

Start. Settings (gear icon). Devices. Printers Scanners. Here we will see all the connected devices and by clicking on the right button we select the item “use by default”.

If the printer will be used periodically, then you can send documents to it in manual mode. To do this, SIMply select the desired device in the print parameters selection window.

In order for the technicians to print documents themselves, a special service is installed in it. Due to a failure or intervention from the outside, it can be disabled or put into manual mode.

The situation can be corrected as follows:

  • Start. Search.
  • Enter the MSC command.
  • The print manager will open, go to its properties.
  • In the general tab, select the “Automatic” startup type, and also click on the “Start” button if it is active.
  • Keeping the actions and see if they gave a result.

All of the above actions solve the main series of problems that can deprive the user of the ability to print. Sometimes the problem is even easier to fix. you just need to restart the computer, and in some situations the antivirus is to blame. That is why, before proceeding to serious actions, you should restart your PC and disable the Antivirus application.

Thank you for attention! Until next time! Best regards, Rostislav Kuzmin.

Reasons for the lack of connection and how to solve problems

If both devices are working properly, the reasons may be as follows:

  • User error when connecting the MFP to a PC.
  • Previously installed drivers are out of date, unstable, or not loaded.
  • By default, another device is selected.
  • Disabled Auto Print Service.
  • Windows operating system errors.
  • Device breakdown.
READ  How To Set The Default Printer

To figure out how to connect a printer to a computer if it does not see it, we will consider each problem in more detail.

Default devices

If other MFPs were connected to the laptop, and later users connect, for example, a Canon printer, it may NOT print Queued files, because it is not selected by default. The error can be corrected as follows:

  • In the “Start” menu, select the “Devices” section.
  • Find what you need.
  • Clicked on it with the right mouse button, select the command “Use as default”.

The procedure may vary slightly depending on the OS installed. For example, in Windows 10, first select the “Settings” item, and then go to the “DEVICES” folder.

After the actions taken, there will be a permanent connection.

Why the pc can’t see the printer via usb

Check the integrity of the wires and contacts

If the computer does not see the printer, then the first thing to do is to check the serviceability of all types of connections and the integrity of the wires. The most common prerequisite for this problem is SIMply bad contacts in the cable. That is why it needs to be pulled out, cleaned and put back in several times. And this must be done, both in the printer and in the computer itself.

Disabled print service

Sometimes the computer does not see the printer when the print service is disabled, so the printer refuses to print. You can fix the problem by going to “Start”. “Control Panel”. “Administrative Tools”. Find “Services” in the list and name it twice.

Next, select “Print Manager”, just click on it twice.

In the services table, you need to make sure that “Running” is listed in the “Status” column. If not, then click on the “Start” button and select “Automatic” in the “Startup type” field. Then at the bottom they will name the button “Apply”, then on “OK”.

Automatic printing

If, due to an error or malfunction, the automatic printing service is disabled on the computer, the MFP may NOT work. How to check it?

  • In the “Start” menu, select the “Control Panel”.
  • Then go to “System and Security”.
  • Find “Administration”.
  • Open the item “Services”.
  • Select “Print Manager”.
  • Right-click to go to “Properties”.
  • Check the box “Automatic”.
  • Check “In Progress” status.

If the printer is connected to the computer, but it does not see it, it is possible that there is a problem with the operating system. You can check this by connecting the device to a second PC. Such errors can only be fixed by reinstalling the system.

If the above methods DO NOT help fix the problem, and the user is still worried about the question “why the computer does NOT connect the printer“, he should contact the service center specialists. Competent employees will fix the breakdown, if any, or point out mistakes made when setting up.

When all the reasons are eliminated, it remains to correctly connect the MFP to the computer. This can be done in several ways, which will be described below.

Operating system crash

If all of the above methods did not help, then a failure in the operating system remains. In this case, you will have to diagnose Windows. The reasons for the failure can be:

  • The presence of viruses in the system;
  • Blocking by antivirus;
  • Incorrect BIOS settings.

To find out if there are viruses on your computer, you should scan it for viruses using antivirus software. over, it is better to check with Several tools, launching them in turn. This provides a more reliable check.

Sometimes antiviruses themselves block the operation of certain actions, mistakenly “thinking” that a virus is running, so they can also conflict with the printer drivers. To avoid such a conflict, just turn off the antivirus while installing the drivers.

Using the BIOS, you can configure the components of the system unit and other important parameters. Sometimes the BIOS itself can be incorrectly configured, which is fraught with Incorrect operation of USB ports. Launched the BIOS, you need to check the state of the ports. You need to focus on the names of options such as USB Function, Legacy USB Port and USB Controller Mode. Then you need to turn on the controller and select “Exit and Save Changes”.

Drivers are missing or not working correctly

If the drivers have not been installed previously, it is important to do so immediately. The software disc is usually included with the MFP when you purchase it.

How to connect a printer without a disk to a computer? If there was no disk or it is lost, you can always download the latest drivers from the manufacturer’s website. For example, to connect an HP series to a computer, you should go to the official page of Hewlett-Packard, select the operating system (Windows 7, 8 or 10), its bit and download the proposed file.

In the event that the drivers were previously installed and do not work correctly, you should remove the old ones before installing new ones. For this you need:

  • In the section “Add or Remove Programs” remove the program.
  • In the “Device Manager” remove the installed driver.
  • Will launch a new software file.

To run the installer, in the folder that was downloaded, find the Setup file.

Incorrect connection

The most common precondition for why the computer cannot see the printer via USB is the wrong connection. You must first make sure whether the printing device is connected to a PC or laptop at all. If this is not the reason, then you need to pull out the USB cable from both devices and insert it into the connectors again until it stops.

Some modern printers use USB 3.0 for connection, while most computers have 2.0 connectors. It is worth considering this, read the instructions for connecting.
