Phantom print jobs, HP P1505

[gherrick]

Running a Mac, OS X.5.8. "Phantom print jobs" means that when I have the HP P1505 set up as best I can [it was previously working just fine; can't suggest what has changed], and I direct a print job to it, connected with USB; the job instantly shows as "complete" in the printer's window [name?], despite the fact that the printer has done nothing, and will do nothing. Restarting the printer or the Mac has no effect.

I've removed the printer from the printer list [Sys Prefs Print & Fax control panel]. Downloaded, from HP, "driver ljP1000P1500-OSX-fulsol-v1.0.6.dmg" and re-installed the driver, but can't find the PrinterDescriptionDocument [PDD] for it when I try to add the P1505 to my printer list.

Suggestions?
