Generic PCL Printer: Set language version to PCL 5C (PCL 5E is still supported as PCL 5C is a superset of it) and apply a few fixes, including no longer incorrectly processing the 1B 0E escape (it appears that's actually used as part of PCL 5C), fixes the HP Color LaserJet drivers when outputting to PDF.
