Network Printing with HP All in one

I have a home network set up and everything functions
properly, EXCEPT priting from the Client computer (Win XP)
to the HP Officejet 3320 (all in one machine) connected to
the host computer (Win XP also) through a USB port
(parallel port works fine). I would use the paralell
port, but I have a Tektronix 560 Extended attached to
it). The print job is sent properly, but will not print
on the Host. Printing directly from the host computer,
and scanning capabilities both work fine.

I can get network printing to work properly if I change
the driver to "USB Printer Support", instead of the
default driver used by HP (IEEE Controller). However,
when I do this, I lose scanning ability from the host
computer.

I understand that there may be a hotpatch from Microsoft,
but I'm not sure if my problem is excactly what the hot
patch fixes. Does anyone know of this problem, and is it
a network printing problem, a IEEE driver problem or a USB
driver problem?

Thanks
