Windows 11 Update KB5050092: Printers Print Gibberish

Windows 11 Update Causes Printers to Speak in Gibberish
A recent preview update for Windows 11—specifically KB5050092—has left many users scratching their heads as printers start spitting out what appears to be gibberish in foreign languages. If your printer suddenly begins printing out unexpected phrases and nonsensical symbols instead of your intended document, take a deep breath: it's likely not a hardware malfunction but a side effect of a software bug introduced by the latest Windows 11 release.

What’s Happening?​

Microsoft rolled out KB5050092 in preview at the end of January, and while it aimed at improving system functionalities, it inadvertently introduced a rather bizarre issue. Users have reported that their printers, especially those with USB-connected dual-mode capabilities, now sometimes print out arbitrary text. Instead of your usual report, your printer may output a string starting with something like "POST /ipp/print HTTP/1.1"—a header typically associated with the Internet Printing Protocol (IPP). This header appears right at the beginning of printouts, followed by other IPP-related information, causing documents to look as though they’re written in an unfamiliar language.

Key Points​

  • Update Details: The problematic update, KB5050092, was released in preview, meaning it hadn’t yet undergone full production testing.
  • Affected Devices: The bug primarily affects USB-connected dual-mode printers that support both USB printing and IPP over USB.
  • Trigger Conditions: The issue tends to occur more often when the printer is powered on or reconnected after being turned off.
  • Unintended Outputs: Instead of a standard printout, users may see technical headers or arbitrary text, with IT professionals noting the presence of "POST /ipp/print HTTP/1.1" at the onset of printouts.
  • Additional Disruptions: Besides the printer issues, there have been sporadic disturbances reported with certain Citrix software, compounding frustrations for enterprises that rely on these systems.

The Technical Backdrop​

When dealing with printing issues like these, it’s important to understand the role of the Internet Printing Protocol. IPP facilitates printing over networks, and many of today’s modern printers support dual modes to offer flexibility between direct USB communication and network-based printing. In the case of the KB5050092 update, a miscommunication between the Windows printing subsystem and the printer’s firmware appears to cause the IPP headers to manifest in the final print output rather than being handled silently behind the scenes.
This kind of technical misstep highlights the complexity of ensuring every component—from operating systems to peripheral devices—works harmoniously together. It also underscores a cautionary tale for both everyday users and IT departments, reminding them that even trusted updates can sometimes lead to unexpected operational quirks.

What Can You Do If Your Printer Is Affected?​

Microsoft has not left users in the lurch. The company recommends using the Known Issue Rollback (KIR) feature, which is designed to reverse problematic non-security updates. Here’s what you can do:
  • Activate KIR: This built-in Windows feature allows you to roll back the KB5050092 update temporarily until a fixed version is released.
  • Reboot Considerations: Since the issue seems aggravated when a printer is turned on or reconnected, ensure you perform the rollback before rebooting or reconnecting your printer.
  • Stay Informed: The fix is slated to be automatically deployed in a forthcoming OS update, so it’s worthwhile to regularly check for updates and stay engaged with Microsoft’s advisories.

Broader Implications for IT Professionals​

For IT administrators, especially those managing networks with multiple devices such as in enterprise environments, these kinds of update issues can be particularly disruptive. Not only must IT teams be vigilant about peripheral behaviors—like printers, scanners, and other connected devices—but they also need to mitigate the ripple effects these issues can have on productivity. In environments utilizing Citrix or other remote desktop solutions, even minor glitches can cascade into larger systemic problems.

A Few Considerations:​

  • Beta Updates and Testing: This incident reinforces the necessity for thorough testing before rolling out preview updates in production environments.
  • Communication with Vendors: Enterprises should maintain clear lines of communication with both Microsoft and peripheral vendors to ensure quick resolutions when such issues arise.
  • User Awareness: Informing end-users about potential quirks associated with preview updates can help in reducing panic and in managing expectations during the troubleshooting process.

Expert Analysis and Final Thoughts​

This printer debacle is a reminder of the inherent risks when dealing with preview builds. While these updates promise new features and improved performance, the early release nature means that glitches are still likely to creep in. For users who encounter these issues, the KIR feature provides a safety net, but the ideal solution will come in the form of an automatic fix in future updates.
It’s worth pondering: how many other hidden quirks might be lurking in our everyday systems, waiting to be exposed by the next operating system update? It also highlights the balancing act that companies like Microsoft face. On one hand, innovation demands rapid delivery of new features, while on the other, stability requires rigorous field testing—a process that often seems to lag behind in our fast-paced digital world.
The bottom line? If your printer starts churning out text that seems to be speaking in tongues, don’t panic. Instead, take advantage of the Known Issue Rollback feature and await the next official fix from Microsoft. As always, keeping your system updated—while remaining informed about potential pitfalls—is the best strategy to ensure your technology works seamlessly for you.

This situation serves as a stellar case study in the challenges of software updates. By maintaining a cautious approach and staying engaged with official advisories, Windows users and IT professionals alike can navigate these hiccups with confidence and minimal disruption.
