HP LaserJet 1320 stops printing

I have a shared HP LaserJet 1320 connected with USB port to a win xp machine that stops accepting print jobs after 15-25 minutes. It prints fine for about 15-25 minutes and then
any jobs sent to the print queue will sit and then error out. If I cycle the power, it starts to print again.I am unable to figure out what exactly the problem is? Please help me out in this regards…
