Printer Not Responding To Commands

My printer suddenly stopped working. When I click on the
print button, the computer starts sending the info to the
printer. The power button on the printer starts flashing
as it should when receiving the print information. The
printer will then start advancing a page to the start
position. At this point the advance button on the
printer starts flashing and the printer stops
responding.

I've tried hooking up another printer and cable that I
know worked properly and ended up with the same results.
The printers will also not respond to internal testing
commands. When I open the active print file it will show
that the doc. was in the process of being sent, but under
the status it states "Error Printing" No indication as
to what the cause is. Print drivers are updated and
working properly according to HP Online Testing.

This seems to be a communication problem originating from
the PC itself or possible problem within XP's print
commands? Has anyone had this same problem or know what
needs to be done to correct it? Print commands are also
needed in order to operate other processing equipment.

I appreciate any assistance in this matter.
