I am about to purchase a J4135 JetDirect adapter card for an HP 5M with 32mb memory and Postcript SIM installed. Has anyone tried to use this card under OSX? I believe that 10.6 was the last version to use AppleTalk, which this adapter also has, but my iMac runs 10.4 Tiger, and I want to use USB and add a duplexer. Please advise if this will work and any special things I need to know before I buy and try this. Thanks!
