I just bought a fantastic iMac with Mac OS 10.4.9. I conected my HP Color Laserjet 3500 (wich is supported by Mac OS as mentioned on the HP website) and the printer installed itselves. Everything looked fine (the image of the printer was the right one) untill I tried printing... Every print I start stops a couple of seconds later with the message 'Printjobs stopped'. I tried everything (setting permissions right, installing the driver I downloaded from the HP website,...). But nothing seams to work. Any suggestions?
