It’s been a tough time for Microsoft when it comes to printing on Windows 10. The company has found itself embroiled in a series of security flaws and bugs. To mention just a few, in early July, the company acknowledged a security vulnerability in the Windows Printer Spooler service, and subsequentlyreleased an emergency fix, but that fix caused issues with select printers. Since then, by mid-July, the companywarned of another security vulnerability in the Windows Print Spooler service, going as far as to advice that customers disable the service.
Now, the July security update that was released has been found to cause problems with printing and scanning on some systems (viaBleeping Computer).
The issue impacts devices that use smart-card authentication, on a domain controller.
In apublished reporton the issue, Microsoft explains the problem:
After installing updates released July 13, 2021 on domain controllers (DCs) in your environment, printers, scanners, and multifunction devices which are not compliant with section 3.2.1 of RFC 4556 spec, might fail to print when using smart-card (PIV) authentication.
There are numerous systems impacted, both client and server versions of Windows 10 and Windows Server, with Microsoft providing a list of all known systems that may experience problems.
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
Devices that use smart-card authentication should function normally when using a username and password for authentication.
This issue has come about as part of a security fix released by Microsoft in the Windows 10 July Security Update. Whilst the intention of the update was to harden the system against security flaws, it has had a knock-on effect of causing printing problems. It is recommended to check that affected devices have the latest drivers installed. Should updating not resolve the problem, the manufacturer of the device should be contacted, to request that an update be made available to resolve the problem, in order to make the device compliant with the latest security patches.
