Microsoft has released an emergency fix for printing issues affecting Zebra and Dymo receipt or label printers caused by changes in the recently released KB5003690, KB5004760, and KB5004945 updates.
Thursday night, Microsoft released an emergency fix for Windows 10 2004, Windows 10 20H2, and Windows 10 21H1 to resolve these issues.
"After installing KB5003690 or later updates, you might have issues printing to certain printers. Most affected printers are receipt or label printers that connect via USB," Microsoft stated in a new issue posted to the Windows 10 health dashboard.
When Microsoft releases new cumulative updates to fix a bug, the new changes may cause other issues in Windows 10.
Using diagnostics and telemetry shared by Windows 10 computers, Microsoft can detect when issues arise and determine how wide an impact they have.
If the issues are affecting a large population of Windows 10 users, Microsoft will issue a Known Issue Rollback through Windows Update that disables the change causing the issues, as shown below.
