Have you tried using the HP XP driver for that machine?

I find that VISTA is very tolerant of old stuff -- I'm running an HP
SJ5P scanner that is much older than your printer!
You may have to get guidance on how to deal with it if VISTA starts
shouting about driver certificates -- I've not run into that yet
myself.
Good luck.
PS Newegg the other day showed the lovely PS8250 for $75. It's worth
every penny of the $199 I paid for mine!
