In article XLhGd.3135$Vx2.176@trndny01, says...
So you just received your brand new Windows XP Home
Edition computer and are in the middle of moving all of
your hardware and software over to the new computer
with its new operating system -- which turns out to
be a major pain -- but you persevere in all this and
throughout the process are heartened to find that your
old reliable HP Deskjet 722C printer is printing just
as well from the new computer as it was from the old.
But then you click on the 722C driver tools icon on the
desktop -- maybe you need to align a new printer ink
cartridge or maybe you just want to see if it works --
and instead of getting your old familiar printer
driver tools you get a nasty little window that says:

Printer Driver Problem
Data required by the printer driver cannot be found
or has been corrupted.
Restart Windows and try printing again

So you click "Cancel" (which is the only choice
you get) and the window disappears (you can get
it back esaily enough by re-clicking on the printer
driver tools icon) and you know that restarting
windows isn't going to fix anyting because you
have restarted it many times in the process of
setting up your computer

So you restart your computer and that doesn't help
(of course)
So you go out on the network to look for the HP Deskjet
722C XP printer driver and (after some searching) you find
a window at the HP web site:

http://h10025.www1.hp.com/ewfrf/wc/d...&lang=en&cc=us

and it says:

There is no need to download a printer driver from the Web.
The drivers for HP Deskjet printers are included in Windows XP.

Well that's a little grim. Here you are using the 722C driver
that came with your version of Windows XP and none of the
printer driver tools will work. Well you consider letting
well enough alone -- after all the printer is working
perfectly -- but then you remember that one of the nice
things about this printer is the great print job it does
and you wonder if it will continue to produce crisp sharp
prints if you can't align it when you change the cartridges.
And you realize that sooner or later you will have to re-align
the printer ink cartridges or buy a new printer. So you decide

Gee Whiz - my old HP 720C is working just fine on my sister's computer
running XP since the day I took it over and plugged it in. Many
cartridge replacements and aligns and no grim yet!
