Microsoft released the optional non-security update (KB5053657) to Windows 10 and 11 yesterday. These updates are typically intended for testing purposes and, if found to be stable, are incorporated into the following month’s stable B-class updates.
An update issued by Microsoft in late January 2025 introduced a problem affecting Windows 10 version 22H2 and Windows 11 versions 22H2 and 23H2, whereby connecting a printer might result in the device randomly printing unintended content. Specifically, printers could unexpectedly output material containing code-related data at arbitrary times.
On affected systems, users may notice printed text beginning with “POST /ipp/print HTTP/1.1,” followed by issue titles and descriptions pertaining to the Internet Printing Protocol (IPP).
Microsoft stated in a prior bulletin:
“After installing this update, you might observe issues with USB connected dual-mode printers that support both USB Print and IPP Over USB protocols. You might observe that the printer unexpectedly prints random text and data, including network commands and unusual characters.”
The issue is more likely to occur when the printer is powered on, connected, or reconnected. It is particularly prone to arise when the print spooler sends IPP messages to the printer on a Windows 10 or 11 system where the driver has been installed.
Although Microsoft has now resolved the issue, we do not recommend installing optional non-security updates, as these testing builds may introduce unforeseen complications. Users are advised to wait for the stable April release.
For enterprise IT administrators, it is advisable to test these updates in a controlled environment. If the updates are verified to function correctly and do not interfere with enterprise software, they can be deployed promptly once the April stable release becomes available.
