Uninstalling the Printer

If your driver printer is unavailable, you can try to uninstall and then reinstalling the printer. Most of the time, this should fix the issue immediately.

Just go to Control Panel and then Devices and Printers. You should see the printer(s) there. Choose the problematic printer and right-click and choose to remove the device.

After removing the printer, go to the Control Panel again. This time, select Programs. You can also use a shortcut: press the Windows key and R then type ‘appwiz.cpl’ and you should land on the same window.

The next thing to do is to uninstall all of the printer’s software and application. Be sure to do this process thoroughly.

When it is done, disconnect the printer from the computer, shut it down and leave it for about 10 minutes. Next, start the computer and reconnect the printer.

The computer should automatically detect the printer and install the drivers. Make this printer as the default printer and put it to a test to see if the problem is solved.
