What you need to know

  • Microsoft confirmed a new printing issue caused by a Windows 10 update sent out earlier this month.
  • The issue only affects printers and scanners with smartcard authentication.
  • Microsoft is working on a mitigation for the issue.

Windows 10 continues to have printing issues. Now, the most recent patch for the operating system causes some printers and scanners to fail to print. The patch came in a security release that addressed the PrintNightmare security issue but causes some other problems related to printing.

Microsoft lists (opens in new tab) the following as a known issue for Windows 10 build 19043.1110 (KB5004237):

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.

The patch started rolling out on July 13, 2021, but Microsoft didn't confirm the new issue with printers and scanners until July 23, 2021.

Fortunately, this issue only affects a small subset of printers. Microsoft says that only printers with smart card authentication are affected, so many of the best printers aren't affected. The problems are also related to whether printers support certain keys or controllers, according to Microsoft (opens in new tab):

The affected devices are smart card authenticating printers, scanners, and multifunction devices that don't support DH or advertise support for des-ede3-cbc ("triple DES") during the Kerberos AS request.

Microsoft advises people experiencing the issue to make sure that devices are running the latest firmware and drivers. Then, the company encourages people to contact device manufacturers. Microsoft is also working on mitigating the issue.

The company notes that "Devices that are affected when using smart card (PIV) authentication should work as expected when using username and password authentication."

  • I have one of the latest Epson printers. And it doesn't recognize any of my PC's anymore. I can now only print from the mobile app till this is fixed. So "The best" is absolute nonsense.
  • The printer-related problems with Windows 10 continue even with the latest update. So many users have reported that Windows 10 is not so compatible with the printers. It affects the working of the printer, which interrupts printing tasks. Microsoft addressed the issue and started working on the updates to fix the printer issues in the Windows 10 operating system. And yet the Windows 10 latest update has printing issues mentioned below: The latest Windows 10 update affects the working of printers and scanners that use smartcard authentication.
    If the login process is done by entering the username and password, the printers and scanners will work fine.
