In the wake of widespread reports of problems with Windows 10 PCs connected to USB printers, Microsoft said it would fix the issue.
“After installing KB4557957, certain printers may be unable to print,” a Microsoft support document explains. “Print spooler may error or close unexpectedly when attempting to print and no output will come from [the] affected printer. You might also encounter issues with the apps you are attempting to print from. You might receive an error from the app or the app may close unexpectedly … This issue might also affect software-based printers, for example[,] printing to PDF.”
KB4557957 is an update that Microsoft issued this past week as part of its monthly “Patch Tuesday” releases. Among its many fixes are “updates to improve security when using external devices … such as printers.” Since issuing this update, Microsoft has also updated its description to include the printing issues it causes. The problems appear to impact Windows 10 version 1903 or newer.
“Microsoft is working on a resolution and will provide an update when more information is available,” the support document adds.
