The most recent Windows 10 update which doesn’t play nice with some printers.
according to Digital trends, the case affects printers from Kyocera, Ricoh, and Zebra. When a user submits a file for printing, instead of actually printing, the whole PC crashes, showing the tragic Blue Screen of Death along with the error code “APC_INDEX_MISMATCH for win32kfull.sys. ”

“We are currently investigating and will provide an update as more information becomes available,” the company said on a support page.
