A significant technical issue has emerged affecting USB printer functionality following Microsoft’s January 2025 Windows updates. The problem impacts devices running Windows 10 (version 22H2) and Windows 11 (versions 22H2 and 23H2), causing unauthorized printing of random data streams. This security concern requires immediate attention from system administrators and end users.
Understanding the Technical Impact
The malfunction stems from the preview update KB5050092 released on January 29, 2025, specifically affecting dual-mode printers that simultaneously support USB Print and IPP Over USB protocols. The most notable symptom is the spontaneous printing of technical data strings beginning with “POST /ipp/print HTTP/1.1” headers, accompanied by various IPP protocol commands. This behavior indicates a fundamental flaw in how Windows handles printer protocol communications.
Vulnerability Trigger Conditions
Security analysis reveals two primary trigger scenarios for this vulnerability: printer power-up sequences and device reconnection events. The critical factor lies in the presence of installed printer drivers, which leads to improper handling of IPP protocol messages by the Windows print spooler service. This interaction creates a potential security risk and resource waste through unauthorized printing activities.
Microsoft’s Response and Mitigation Strategy
Microsoft has implemented an immediate mitigation through the Known Issue Rollback (KIR) mechanism, a built-in Windows recovery feature designed to reverse non-security related problematic updates. This temporary solution helps maintain system stability while development teams work on a permanent fix for future Windows updates.
Enterprise Environment Considerations
Organizations operating Windows devices in corporate environments must implement additional Group Policy configurations to address this issue effectively. System administrators should prioritize the following actions:
– Monitor Microsoft’s official update channels for permanent fixes
– Deploy appropriate Group Policy settings across affected systems
– Maintain detailed documentation of affected printer configurations
– Implement printer access controls where possible
This incident highlights the critical importance of maintaining robust update management protocols and backup systems in enterprise environments. Organizations should establish comprehensive testing procedures for Windows updates and maintain detailed recovery plans for similar incidents. Regular data backups and systematic documentation of printer configurations become essential components of a resilient IT infrastructure strategy. The situation serves as a reminder that even routine updates can introduce unexpected complications, emphasizing the need for proactive security measures and response protocols.
