The programs are quite compatible, except for a couple of things.  There are
quite a bit more animations in Office XP than in Office 2000.  By the way,
NT is probably the version of the Windows Operating System and has nothing
to do with Office!

Printing presentations shouldn't have any impact unless these animation
differences rear their ugly head.  If you are creating a presentation using
Office XP, and you might need to view/show it on an Office 2000 version of
PowerPoint, you can disable the new features (Under "Tools" menu, "Options")
in XP so this problem doesn't occur.  Keep in mind that the file can still
be shown in Office 2000 but the new animations won't work.  Instead, the
objects will just appear when the slide comes up since Office 2000 can't
recognize the new animation.

Hope this helps!

Mary,
as Bill said: the Office resp. PowerPoint versions 2000 and 2002 are
compatible. BUT: As you mention "NT", I suspect that her computer has
Windows NT as the operating system and his has Windows XP (which is a newer
version). Fonts are installed with the operating system and if he used a
font that is not present in her WinNT, she'll get a different print. So the
only thing she might have to do is to install a missing font, not upgrade
the whole system.

Kind regards,
Ute

Were they printing slides from the same presentation?  If not, that could
explain the difference in quality, depending on what the differences were.
