Windows 10: Problems for printers with KB5004945

One of the most affected brands (but not the only one) seems to be Zebra, as we learn from the feedback shared on the forum from the manufacturer: On Windows 10, the LP2844 model connected via USB, no longer prints; the document is queued, but it is not printed. The anomaly is confirmed by other users, which appeared for everyone following the installation of the update KB5004945: We have the same problem with different computers and ZQ530, I think it is attributable to KB5004945.

At the moment, the only way around the bug is to go through uninstall the update. The procedure to follow is the same as always: open the “Settings” of Windows 10, select the item “Update and security”, then “View update history”, then “Uninstall updates” and finally select the one to delete, in this case KB5004945. Alternatively, you can run the command “wusa / uninstall / kb: 5004945 / promptrestart” (without quotes).

However, it must be taken into account that deleting the update exposes your device to PrintNightmare vulnerability. You can manually mitigate it by opening PowerShell, typing the command “Stop-Service -Name Spooler -Force” and then “Set-Service -Name Spooler -StartupType Disabled” (always all without quotes).

But there is good news: Microsoft is aware of the problem and is working to release an additional patch soon. Update management is certainly the aspect that most needs improvement with the arrival of Windows 11, even before the interface restyling and the introduction of new features.
