I have the JetDirect 175x USB to AppleTalk print server. I am printing from both Native OS X apps and Classic apps to by 940c which is being shared over the network by the JetDirect print server.
I just installed the latest version of the HP drivers and setup the AppleTalk printer on the print center.
Aftershock: Thats good if you want to keep your mac on all the time. There is a reason for using a JetDirect server... direct ETHERNET printer networking.
Especially in a office environement it would waste a computer.
Javintosh.... I tried that before but I will try again!! :-D
