I am running OS X 10.5.1 on an iMac, and have an HP AIO 3330 using JetDirect. Worked fine under 10.4 but gives a "trouble communicating" error under 10.5. The AIO works as I can print from my 10.4 MacBook thru airport. I tried a search but had newbie luck (none). HP is a complete joke: "I can connect you to tech support and they will tell you if the driver needs to be replaced. That will be $39.00." Has anyone encountered this? I'm tempted to pound the crap out of the HP and move to Lexmark or some other mfr. Thanks for any assistance.
