HP PSC 900 Series and Windows XP

I'm running Windows XP on a Del Dimension 8100, Pentium II with 512 MB RAM.
Prior to installing Windows, I ordered the HP XP driver CD for my printer
and then reformatted my HD.

I've installed the new driver according to the instructions; however, nowthe
printer will not fax or copy. It simply sits there, FOREVER, in a
"warming up" mode.

I've even tried uninstalling the HP driver and using the driver shipped with
XP; no luck.

Any ideas?

Thanks for your help,

Kit
