I just got a Lexmark z816, which is plugged into the USB port on my Airport Express. When I try to print something, it is recognized through rendezvous, but it automatically stops the jobs. So, if I go to the printer and click on "start jobs" it says "opening printer connection" and then just stops the jobs again. The printer works fine when it is directly plugged into my powerbook, and my airport express works fine otherwise. Any ideas on why this isn't working? I've searched the knowlegebase, etc.
