I am currently using OS 9.2 on a G4 running Quark 5.1 printing to a Xerox Phaser 790. Font manager is ATM. There are 8 users on the network and we did add extra RAM to the printer. The problem is that sometimes the quark document fails to print (gives a message from the printer), sometimes it just flushes from the printer (no message at all). To work around I tried substituting fonts (usually Helvetica), if that doesn't work I "hide" the art from quark so all the links say "missing". There doesn't seem to be any rhyme or reason...and switching to Indesign is not an option at this time.
