Print job doesn't reach print queue
I have a 24" iMac connected to an HP laserjet 1022 through a Dlink print server. Everything worked fine until a few days ago when print jobs wouldn't get to the printer. Print jobs appeared in the print queue but would not print. A message indicated the printer was busy and it would try again. But nothing happened. A Windows machine connected to the same print server works just fine.
I tried reinstalling the printer and driver, but now, the print job doesn't even appear in the queue. In the Print & Fax preference pane, I can see the printer which is "idle".
Any idea what the problem is?
iMac (intel), Mac OS X (10.5.6)
