Very odd. I use 2 different printers on my Airport Extreme base station (Canon i850 and Brother HL1440). Under Jaguar they both worked great. I'm trying to set them up under Panther and only the Canon will work with the AirPort. The Brother either gives Printer Setup the beachball or displays a message saying there was an error creating the printer. If I plug the USB straight into the computer it works fine so I don't think it's a driver issue. Maybe it's not even a Panther issue (most signs point to AirPort) but the only thing that changed is the installation of Panther. Any ideas?
