Microsoft has released several patches today that resolve printer issues in Windows 10 1903 and 1909 versions.
KB4567512 has been released for the above-stated Windows 10 versions to address issues that might prevent certain printers from printing. Reported issues include the print spooler generating error codes or even closing unexpectedly when trying to print which usually resulted in no output from the printer. Another issue is related to apps you’re trying to print from that might close unexpectedly or pop-up an error code when trying to print a document.
This issue also targets software-based printers, like printing to pdf or other file types.
Along with KB4567512, a KB4567513 and KB4567514 have also been released to address the same issue on Windows 10 1809 and 1803 versions.
