Good news, everyone!
I finally uninstalled all of the software associated with any and all Hewlett Packard printers. The culprit, so it seems, was the latest and greatest HP software upgrade for its HP OfficeJet 6100 Series. Lots of great looking imaginng aids, stupid "HP Preview" feature that really sux if you are printing remotely on a LAN... since you have to go to the attached computer to click "OK" and HP tells me that there is no way to disable, cancel, destroy, or castrate the HP Preview handy dandy "feature." Anyway, having removed all of the HP software from my computers, I then reinstalled the BASIC drivers that come with the HP Printers I actually use, and none of the lovely "suite" of "features."
It seems that some nasty agent within the all new (last week) HP software upgrade messes with Microsoft Office's WORD program's file -- Normal.dot
It changed it somehow, so as to make is so very slick for HP. LOL
Anyway, what it was doing was changing it in some way that made Windows XP Professional not be able to see it, although the rest of Office 2000 ran perfectly. It could load the "fake" Normal.dot of course, so the program looked like it was running, but in fact, the documents loaded did not match the "template" WORD needs to have in the background in order to make the tool bars work and make the printing functions valid.
Thus, having removed all of the HP printer software and then only accepting the basic drivers that come from the installed machine alone (excluding all of the "handy" updates HP sends along from its B.S. website, I managed to solve the problem. All features working fine now, and one by one I have added each of the printers I use, allowing only those basic drivers that came with each originally.
I am very new to computers, but this I have learned: At least with respect to HP, what they give you for free on their software website is only worth exactly what you paid for it.
Anyway, thanks, everyone, for helping me out.
