Printer Issue...

[Kevin]

Well it deals with an HP DeskJet 842C USB printer. I am running 1.8GHz
Athlon XP with 700+ Megs of RAM. I'm using the newest kernel
(non-development). I turned it off while the computer was on one day
and ever since then it hasn't worked. I have tried to add a printer
(through the Gnome interface) and it doesn't seem to be working. If I
turn the printer off and on i can rescan and see the printer... but as
soon as I add to and apply changes, the printer doesn't want to print
and is GONE the next time i scan my printer ports. I'm clueless.
