Lately, Microsoft has released an emergency fix for printing issues that affect Zebra and Dymo receipt or label printers caused due to changes in the recent KB5003690, KB5004760, and KB5004945 updates.

This week, Microsoft fixed the actively exploited PrintNightmare vulnerability with the release of KB5004760 and KB5004945 security update.

On installing the update, Windows users discovered that they no longer could print to their Zebra and Dymo label and receipt printers connected with USB.

After installing the updates most people reported that the problem was associated with the patch for the PrintNightmare Vulnerability.

Though, Microsoft announced today that the issues are not associated with CVE-2021-34527 or CVE-2021-1675 and are caused by modifications introduced in the June 2021 cumulative update preview.

Fixed utilizing Known Issue Rollback feature

Late Thursday night, Microsoft issued an emergency fix for Windows 10 2004, Windows 10 20H2, and Windows 10 21H1 to fix these issues.

Microsoft posted to the Windows 10 health dashboard and said that on installing KB5003690 or later updates (including out of band updates, KB5004760, and KB5004945), you might have issues printing to specific printers. Most affected printers are receipt or label printers that connect via USB.

Microsoft further explains that using the Known Issue Rollback (KIR), the issue is being resolved. However, you must take note that the process may take up to 24 hours for the resolution to be delivered automatically to consumer devices and non-managed business devices. If you want to apply resolution to your device faster, you may try to restart your Windows device.

To identify whether this KIR is installed on your system, you can open the Registry Editor and do confirm if the key exists. If the key exists, the KIR has been installed on your computer.


Don’t panic if you don’t see any KIR in the Registry. It just signifies that KIR hasn’t be pushed into your system yet.

Microsoft says the rollout is anticipated to be accomplished with 24 hours and restarting your PC may boost up this process.
