  • Tweak registry… There is evidence that this works. You need to go to the registry editor along the path HKEY_LOCAL_MACHINE SYSTEM ControlSet001 Control Print Printers * Your printer name * CopyFiles and delete the entire ICM folder.
  • Reinstall printer… Detailed instructions are in the forum thread Microsoftbut in English.
