I'm using an HP DeskJet 5550 as a shared printer. On the computer where the printer is local (via USB), intermittantly, when you print, only a portion of the image or text file will print -- then the page ejects as if the job is finished. No error messages.
What's interesting is that on the computers that are using the printer as a network printer, the print jobs come out fine.
I've tweaked the printing options (spool, print immediately, print direct) but the problem persists. I've completely removed the software, deleted port assignment, downloaded the most recent installer from HP, and reinstalled. Problem persists.
The problem seems like a memory error in the printer -- but as the other networked PC's arent' having the problem, I have to conclude that there's a problem with the local setup.
