Microsoft has released the Windows 10 KB5001649 emergency update to fix printing issues plaguing users since the March 2021 Patch Tuesday updates.
Many users have reported that Windows 10 would crash when printing with an "APC INDEX MISMATCH for win32kfull.sys" error or printed pages would have missing graphics, black bars, or blank pages.
To resolve these issues, Microsoft released an out-of-band Windows 10 update on March 15th that only resolved the printing crashes but did not fix the other printing issues.
Last night, Microsoft released a second Windows 10 out-of-band update to resolve the remaining printing issues, such as blank pages, black bars, formatting issues, and missing graphics.
Microsoft is releasing the fix as an optional cumulative update through Windows Update and the Microsoft Update Catalog and only recommends installing it if affected by the printing issues.
Microsoft has still not provided a reason for these printer issues but it may have been caused by recent security updates that fixed Windows Print Spooler vulnerabilities.
