Brother MFC-7420 Stops Printing
After successfully installing my Brother MFC-7420 under Windows 10 (Version 1904.450) using the built-in Windows 10 driver, the printer stopped working. I tried reinstalling the printer under Add Remove Printers, but the same MFC-7420 gets installed, always with an explanation point under Troubleshoot when the properties of the printer are displayed. I tried reinstalling the printer, but the same printer keeps popping up with the same warning. I tried unplugging it and also removing and reinstalling the device, but always with the same results. Finally, the printer started to work again, although I didn't do anything new. However, it often stops. I tried researching the problem, and there is a hint that Microsoft Update may be to blame, but I cannot find a particular KB to pin it on.
Any help greatly appreciated. I cannot bear the thought of buying a new printer for what is almost definitely a software glitch.
