Cannot re-install HP scanner and/or printer

[Guest]

Using registered Win XP with auto upgrades installed. Been in use for a
number of years with no real software issues. Hardware almost always loads
easily. Recognizes Mem sticks, cameras, MP3 players, etc. with no problems.
Last week I accidently unplugged parallel cable to my HP Deskjet 812C
printer. Plugged it all back in and computer could not find driver. Tried to
re-install from HP CD... get error... "software not designed for Win NT".
Tried on line software upgrade... same info, same error message. Attempted
HP scanner install, (also a parallel device, HP ScanJet 3200C), also with
orig HP install CD... same error. device driver software thinks my op sys is
win NT not win XP. How do I fix?
Thanks...

Fixed problem... uninstalled HP 812C printer and 3200C scanner and purchased
and subsequently installed a new HP 5610v Officejet all-in-one printer with
USB connection. Installation was a breeze. (Exception... next day I plugged
in USB to a different socket.... no printer showed up... Win could NOT
find, etc. etc. I re-booted, re-installed, etc. still no printer... an
hour later, shut off computer and printer, reconnected to orig USB socket,
computer came on normal with printer on line as if nothing had ever happened.
When Windows works, it works and does a good job... when it fails... well,
that is why this site is so busy... read it over.... similar problems every
day... its 100% LOVE/HATE!!!)
