I have an HP LaserJet 4M Plus that sits in the living room and everything in the house connects to it using a JetDirect card fitted in it. It supports AppleTalk and my later OS 9 system could print directly to it but I'm having trouble getting my older System 7.6 Quadra 950 to see it. Did the JetDirect require an extension on older systems? I can't double check my settings on the OS 9 box right now as it was put in storage when I moved several months back.
