Dell 968 printer locks up/won't print multiple pages

Hello all, I have a dell 968 aio, currently connected to my HP laptop running windows 7 64 bit. My problem is printing multiple pages... Not necessarily at one time. After about 10-15 pages, it hangs up about 20% through printing a page. I have installed the correct print driver directly from dell, test page comes out fine, start printing and everything is good until I'm 10-15 pages in, and it hangs. The document won't continue, I have tried multiple ways of canceling it and just restarting it, and the only way I've found to get it back operational (for another 10-15 pages) is to cancel the document, either on the printer or computer, (makes no difference) after canceling it shows in the print queue as deleting and won't go away, so I have to restart my computer once or sometimes twice, and unplug the power to the printer during restart to get it to print again... What is confusing me the most is, I originally had it hooked up to my desktop (Inspiron 530 running xp) and it does the same thing... When it hangs, the printer shows "printing page x of x", and the dell print status monitor shows it printing, but just stops in the middle. Depending on how many pages I'm printing, anywhere from 15 to 66 percent... I'm so confused... Help?!?! Jad
