Downloading the drivers is one thing, properly installing them may be
another.
If drivers from an older windows version are present, they should be
uninstalled before an install is attempted.
If this did not occur properly, it may be necessary to go the mfrs web site
and check for a cleanup utility or an uninstall proceedure that lists
registry entries to be manually removed.
Finally, XP likely changed the mode of the parallel port. You may need to
check it in BIOS, and change it to SPP or ECP. SPP is commonly used for
quite a few older printer models. An older mother board may have alternate
nomenclature for the parallel printer port modes. If so, you may see such
things as PS2, Bidirectional, and the like. Generally, you would try
bidirectional first.
