The Windows 11 23H2 update KB5050092 has been reported to cause USB printers to print random gibberish or unusual characters. This issue affects USB-connected dual-mode printers using both USB Print and IPP Over USB protocols. Microsoft acknowledges the problem, which arises from the interaction between the printer driver and the print spooler. Users can identify the issue if their printer outputs pages starting with "POST /ipp/print HTTP/1.1." Microsoft offers a Known Issue Rollback (KIR) to revert to a previous state before the update. Similar printing issues have been reported by Windows users in the past.
