Getting an UFR-II Raster Graphics mode error message when trying to print to a Canon ImageWriter Advance Printer. To fix:
Open an application, choose print
Choose Print Preview
In the Preview application, choose print
To the right of the name of the printer is a downward arrow \/
Clicking that will expand out the printer properties. There is a dropdown button labeled Preview. You now have a button named Quality Settings. Click that. Change the Graphics mode option from UFR-II to Raster mode. Choose ok. Now save this setting under a new name and make the default.
