Microsoft says customers may experience printing and scanning issues on devices using smart card authentication after installing July 2021 Windows 10 security updates on a domain controller.

Windows 10 users who encounter this issue are advised to first check if they have the latest drivers and firmware installed on the non-compliant and misbehaving printing or scanning devices.

If the known issue still appears even though the devices are up-to-date, affected customers should contact the device manufacturer and ask for setting changes or updates to make the printer or scanner compliant with CVE-2021-33764 hardenings deployed via July Windows 10 security updates.

Redmond addressed Windows 10 printing issues caused by changes introduced in the June 2021 cumulative update preview earlier this month.

Users also encountered printing issues in March after installing the March 2021 Patch Tuesday updates, reporting that Windows 10 would crash when printing or print jobs would be missing graphics elements, blank pages, or other issues.

To resolve these issues, Microsoft released two out-of-band emergency updates for Windows 10 one week later: KB5001567 on March 15 to fix blue screen crashes when printing and KB5001649 on March 18 to fix the printing issues.
