Hey There, I am Sofia Carter. Here are a few things to fix the Windows 10 Printer Driver Is Unavailable issue. First, check to see if your printer is turned on and connected to your PC. If it is, then try restarting both your printer and your PC. Try uninstalling and then reinstalling your printer's driver if that doesn't work. Further, you can usually do this through your PC's Control Panel. Finally, if all else fails, you may need to contact your printer's manufacturer for help.
