Recently installed a new konica minolta Printer at a customer ( BizHub C659 ) on a Server 2012 R2 Machine , however randomly the driver would crash the Printer Spooler below in the event log

This was interesting because the same style driver ( PCL 6 ) for the previous Konica Minolta ( KOAZCJ_C.DLL ) had worked fine

The only resolution was to change to driver to konica minolta universal driver v3
