Well, my new printer works great with OO Writer, Firefox and the like.
When I open a pdf in Evince and try to print it, the (CUPS) dialogue picks up on lots of nice professional print options that standard Office apps tend not to, such as print quality. But the printer status is reported as "Rejecting jobs" and the Print button is greyed-out.
XPDF doesn't render properly at all.
I'm kinda fazed, this was mainly what I bought the printer for.
