How to solve the problem that win10 cannot find the printer device

It is usually caused by driver problems. Microsoft explains that this is because the related software has not been successfully migrated after upgrading to Windows 10.

1. When Win10 encounters printing problems, how to solve it?

Problem 1: Unable to install driver.

When installing a print driver in Win10, if the supporting printer is an older one (such as a dot matrix printer), the prompt "Third-party INF does not contain digital signature information" will often appear, causing the installation to fail, and even some The driver gives no clues. In this case, people often look for new drivers or try out each version of the driver one by one. But for older products, such methods are often ineffective. In fact, the reason for this problem is that Win10 uses forced digital signatures. If you turn off this function, you can successfully install the driver. Especially the driver on Win7 can be successfully installed in Win10.

The shutdown method is as follows: In "Settings", select "Update & Security", click "Restart Now" in "Recovery" and the computer will enter On the "Restart" page, select "Troubleshoot" → "Advanced Options" → "Startup Settings", then select "Disable driver signature enforcement", and finally click "Restart". After the computer restarts, you can install the driver.

Problem 2: The printing program cannot be started.

When printing, Win10 reports the prompt "Unable to connect to the printer, the spooler is not running." When encountering this situation, many people choose to reinstall the driver, unplug and unplug the USB cable, or restart the computer.

In fact, the prompt has made it very clear that the problem lies in Windows' own printing service. We can find "Print Spooler" in Win10's "Control Panel" → "Administrative Tools" → "Services" , it is the print background service. Double-click on this service to pop up the "Properties" menu. In the "General" submenu, set the "Startup Type" to "Automatic", and click "Start" in the "Service Status", and then Click the "OK" button to start the print background service. Try printing again, everything should be fine.

Question 3: The default printer has been modified.

The printer was obviously used normally, but when I used it again after a few days, I suddenly found that I could not print. After a closer look, I found that several printers had been added inexplicably, and the default printer was set to the newly added printer, so You can only reset the default printer, or specify the printer when printing, but the problem is that it is too troublesome to specify the printer every time you print. What should you do if you reset the default printer and accidentally change it again?

Actually, this problem occurs mainly because many programs, such as Office, Adobe Reader, etc., will automatically generate virtual printers after installation. In Win10, the default is "Set the last used printer as the default printer." ”, so that when the program calls the virtual printer, it changes the default settings of the original printer. In this case, you can go to "Settings", select the "Devices" option, under the right side of the "Printers & Scanners" menu, change "Let Windows manage the default printer" to off, and then go to "Control Panel" In "Devices and Printers" under "Devices and Printers", find the printer device you want to set as the default, right-click and select "Set as Default Printer". The default printer will not be modified for future use.
