HP M477 Print Quality

I have installed PrintFab for use with my HP M477 Pro. It works, but I am unable to select a print quality above 300 dpi. When I select 600 dpi (which printer should support) the printer crashes with an "Error 79" message and the print job sticks in the print queue. Is there another setting somewhere to fix this and allow printing at 600 dpi?
