Microsoft Update Sparks Printer Mayhem: What You Need to Know
It seems that in the realm of software updates, not everything always goes according to plan. Recent reports confirm that a Windows update—specifically one affecting Windows 10 and some builds of Windows 11—has led to erratic printer behavior for numerous users. If your printer is printing random text, network commands, or even unexpected headers, you’re not alone. Microsoft has officially acknowledged the issue and initiated a Known Issue Rollback (KIR) to help affected customers restore normal functionality.The Unintended Consequence: Phantom Printouts
The problem centers around a particular class of printers: USB-connected dual-mode printers that support both USB Print and IPP Over USB protocols. After installing certain recent updates, these devices have begun autonomously printing garbled data. Among the most curious symptoms is the onset of printouts starting with the header:Following this line, users have reported that their printers output additional Internet Printing Protocol (IPP) related headers and even random data, seemingly without any command from the user. This behavior is both baffling and disruptive—particularly in an office environment where unexpected printouts are not only a nuisance but can also potentially lead to wasted resources or sensitive data exposure."POST /ipp/print HTTP/1.1"
Key Points:
- Affected Printers: USB-connected dual-mode printers that work with both USB Print and IPP Over USB.
- Symptom: Phantom printing of network commands and random characters starting with a standard IPP line.
- When It Occurs: Often when the printer is powered on or reconnected after disconnection.
Which Windows Versions Are Affected?
Not all Windows updates fared equally. Microsoft has indicated that the issue primarily affects devices running specific versions of Windows 10 and Windows 11. Here’s a breakdown:- Windows 10 Users: Particularly those on version 22H2 who installed the update attached to KB5050081.
- Windows 11 Users:
- Affected: Those on Windows 11 22H2 and Windows 11 23H2 (and the January 2025 Windows preview update, KB5050092, amongst later updates).
- Not Affected: Users on the latest Windows 11 24H2 appear to be in the clear with no reported phantom printing issues.
Quick Recap:
- Safe Zone: Windows 11 24H2 (no reported issues).
- Warning Zone: Windows 10 22H2, Windows 11 22H2, and Windows 11 23H2 experiencing unexpected printouts.
The Technical Underpinnings: How Does This Happen?
Understanding the why behind the erratic printouts involves delving a bit into the technical details:- Dual-Mode Printer Dynamics: Dual-mode printers equipped with support for both traditional USB Print and the more modern IPP Over USB protocols can sometimes confuse the communication sequence. The dual support, while generally advantageous, creates a scenario where the printer driver might inadvertently send IPP protocol data instead of standard print jobs.
- Role of the Print Spooler: In these affected versions, the Windows print spooler—responsible for managing print jobs—seems to be dispatching IPP protocol messages inappropriately. This misdirected traffic appears to cause the printer to interpret the data as a print job, leading to the random printing of what should merely be background protocol communications.
- Trigger Events: The issue is more pronounced when the printer is either newly powered on or reconnected to the system. These moments, which reset the connection dynamics, likely trigger unwanted protocol negotiations between the OS and printer hardware.
Mitigation: The Known Issue Rollback
Facing mounting customer feedback and internal evaluations, Microsoft has rolled out a Known Issue Rollback (KIR). For many users, applying the KIR has been sufficient to revert the problematic behavior back to the expected norm. This solution involves reverting to a previous update version that did not cause the erroneous printouts.Steps for the Regular User:
- Check for Updates: First, verify your current Windows version. If you’re on Windows 10 22H2 or Windows 11 22H2/23H2, you might be affected.
- Visit the Update Advisory: Microsoft’s advisory provides step-by-step guidance. While the details are more straightforward on the advisory page, the process generally involves running the Known Issue Rollback tool.
- Confirm Success: Once rolled back, test the printer by powering it on or reconnecting it to confirm that unexpected printouts have ceased.
Advice for Managed Devices:
System administrators managing fleets of devices need to be particularly vigilant. Given the erratic behavior noted in this update:- Group Policy Adjustments: Administrators are advised to leverage Group Policy to remove or disallow the problematic update on managed endpoints.
- Monitor Updates Closely: Consider deferring updates until this issue is fully resolved for your environment.
- Document Rollback Procedures: It may be beneficial to distribute a brief guideline or memo internally that details how to revert the update in case any unexpected printer issues arise.
Implications for the IT Ecosystem
This incident serves as an important cautionary tale in the dynamic interplay of software, hardware, and network protocols. Here are a few takeaways for IT professionals and Windows enthusiasts alike:- Vigilance in Updates: Even routine updates can have unexpected side effects.
