Comment 25 for bug 777670

I too have this problem, I did a fresh install of Natty to a new partition, and have only copied data files over from 10.10.
I print a test page from 11.04 using the default hpcups 3.11.1
Output Mode = Color Print Quality=Normal and the red line goes black to green, green line dark blue to white, black to blue etc.
Output mode = Color, Print Quality=Best and It just prints out a PCL XL error subsystem kernal error: IlligalDataValue, Operator VendorUnique Posisiton 7, and another blank page.

Reboot to my 10.10 and it works just fine. (although I remember with 10.10 I did have a problem printing color images in grey scale draft mode it would just print a very similar PCL XL message on the paper)
