I want to print from my Mac to a HP DJ 520 which is connected to the Linux box where magicfilter with the DJ 500 filter is installed. Can anybody recommend a good PPD file? I tried the HP LJ III (si) so far, without luck. Because I do not know what to look for I fear I have to check out every PPD file available unless I find somebody who suggests a good one for a DeskJet 5xx.
