uninstall officejet software

when i attempt to uninstall hp all-in-one software in xp,
i don't get an option to "change/remove"

I get it on all other programs in the list just not on
the "hp officejet d series" which is 231 MB and I want to
make sure I do a clean uninstall.

The reason for doing the uninstall is that the printer is
not recognizing the PC (or the reverse) and I am not able
to scan.

HP says to do a remove/uninstall and then a reinstall
because of XP. My machine started out with W2000 Pro and
was upgraded to XP.

Thanks for any help.
