Microsoft has released a cumulative out-of-band update to fix a known printing issue preventing some printers and scanners from working correctly.

"Addresses an issue with devices that do not comply with section 3.2.1 of the RFC 4556 specification," Microsoft explains in the KB5005394 support document.

"Noncompliant printers, scanners, and multifunction devices might not work when you use smart card authentication (PIV). This issue occurs after you install the July 13, 2021 update on domain controllers (DC) in your environment."

Fixed on a limited number of affected Windows versions​

The printing issues affect both client and server Windows platforms, starting with Windows 7 SP1 / Windows Server 2008 SP2 and later:
  • Client: Windows 10, version 21H1; Windows 10, version 20H2; Windows 10, version 2004; Windows 10, version 1909; Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10 Enterprise LTSC 2016; Windows 10, version 1607; Windows 10 Enterprise 2015 LTSB; Windows 8.1; Windows 7 SP1
  • Server: Windows Server, version 20H2; Windows Server, version 2004; Windows Server, version 1909; Windows Server, version 1809; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2; Windows Server 2012; Windows Server 2008 R2 SP1; Windows Server 2008 SP2
However, based on the support document published today, the KB5005394 cumulative update released today by Microsoft only applies to Windows 10 1809, Windows Server 1809, and Windows Server 2019.

This out-of-band update can only be installed manually as a standalone package available for download through the Microsoft Update Catalog.
