My mother has a Mac Mini (1.5 Ghz G4) and she's having quite alot of problems with printer drivers. She first had an HP 5440 and it started printing without black. It would print black the first page but then would just print in color. So we then printed with a Lexmark X515 and it did the same thing. I tried the updated company drivers and generic GIMP drivers. Both gave me the same results. Also messed with every Quartz filter and paper quality. On top of that, I did a reinstall of the system (not a clean install) and it's doing it again. I'm guessing it's the some sorta printer cache. I did permissions repair BTW. What could be making the printers do this? I don't want to revert to a clean install, but it may be the only way to completely fix the situation.
