All Printer Drivers Became Inaccessible or Stopped Working after a Windows Update:
OS Edition WIN 10 Home; Version 1803; Build 17134.48; Installed 05/12/18
Since last Windows 10 update on 5/12 all my printers stopped working.
When I try to print from an application a full list of printers appears. Some printers (e.g. Microsoft Print to PDF) is greyed out and cannot be selected, others can be selected but none works.
Settings/ Printer Scanners Does not show any printer. When I tried Add a printer, no printer was detected including my USB connected HP Printer.
Device manager shows no printers.
There is no place to select any printer and update driver.
All the missing printer drivers are listed in the Setting///Print Server Properties/Drivers
Printer troubleshooter detects all the printers but all it does is to allow me to make any printer my default. Still nothing works.
I tried all the Microsoft published fixes that I found. Nothing works.
I reinstalled my HP printer using HP app. It is now showing on tools/printers and on Device Manager.
I tried to manually install Microsoft Print to PDF. It is not listed in the printer driver list for Microsoft.
HELP is greatly appreciated.
