In recent developments, users of USB-connected dual-mode printers may find themselves facing an unexpected challenge: their printers are producing erratic outputs, seemingly spouting nonsensical text. This peculiar phenomenon is linked to a problematic update from Microsoft, specifically the Windows 11 23H2 update, identified as KB5050092, which was released in late January.
Understanding the Issue
This update has been associated with various known issues, particularly affecting certain Citrix software. However, the emergence of printers generating random strings of text marks a new chapter in the saga of update-related glitches.
According to Microsoft, the glitch predominantly impacts dual-mode printers that utilize both USB Print and Internet Printing Protocol (IPP) over USB. Users might notice that their printers unexpectedly churn out random data, including network commands and unusual characters. Notably, the printed output often begins with the header ‘POST /ipp/print HTTP/1.1’, followed by other IPP-related headers, offering a rare glimpse into the inner workings of printing protocols and drivers.
Microsoft elaborated that this issue tends to manifest more frequently when the printer is powered on or reconnected after a disconnection. The root of the problem lies in the printer driver installed on the user’s Windows device, where the print spooler erroneously transmits certain IPP protocol messages to the printer, resulting in the unexpected text output.
Implications for Users
Given the rising costs of printer consumables and the often strained relationship between consumers and major printer manufacturers—who may harbor reservations about third-party consumable providers—it’s understandable that users are concerned about wasting valuable ink or toner on nonsensical prints.
To address this issue, Microsoft has indicated that it can be mitigated through the Known Issue Rollback (KIR) feature. IT administrators have the option to deploy a special Group Policy to implement a KIR, providing a temporary reprieve from the glitch.
Looking ahead, Microsoft has assured users that a more permanent solution is in the works, with plans for a comprehensive fix to be included in an upcoming Windows update.
