This means it doesn’t appear to be linked to a specific program or when not printing in Windows. The errorrefers to a mismatched driver and happens when printing from Notepad, Microsoft Word, and other system apps.

There are more than a few factors that trigger this blue screen of death error, so finding and fixing the right one can be a tricky and time-consuming process.

Specifically, the issue appears to be impacting printers from Kyocera, Ricoh, and Zebra. Blue Screen of Death Errors mostly occur due to faulty drivers, hardware errors or corrupted Windows updates.
