I have an HP LaserJet 4000 that I have configured via Bonjour as a Generic/Postscript Printer in Parallels. It usually will print only one document before it seems to lose its connection although it will sometimes print several documents in a row without a problem. I am mostly using MS Works within Windows XP when I encounter this problem. When I go to System Preferences and open the printer dialog, I get a spinning blue and white "barber pole", a message saying "sending data", then "GenericClass: waiting for device" and nothing happens. Sometimes, if I go back to the Mac side of the world and try and print something, it will print everything in the Q. The printer is attached to my Intel iMac via the USB port to the printer via its parallel port. I have tried stopping the job and then restarting but this rarely works. Often it seems to just decide on its own that it is time to resume printing. This is becoming very, very annoying and has made me regret leaving the PC world and coming over to the Mac world.
