Print Preview/Printing doesn't display or print 1/3 of page

[Cat]

1 user w/Office XP
2 users w/Office 2000
All with Windows XP
All using Dell Optiplex GX260
Multiple printers used, both inkjet and laser.
Multiple documents, all several pages long.
Document in print preview does not display bottom half of
page and then when it is printed, the bottom half doesn't
print, either. Have also noted upon occasion that a page
may have "shifted over" and print with several inches of
white space on the left. This could happen to 1 page out
of 16. User closes Word, opens document again and this
time print preview displays entire page as it should, but
may or may not print entire page. After closing and
opening Word an arbitrary number of times, the document
will print correctly.
Have reinstalled printers, checked for most recent
drivers, but doesn't seem to be the printers since this is
showing up in print preview as well. Please help??

Not one of the experts, but FWIW;
Are the printer drivers installed locally?
I've seen weird happenings when the machines use a network driver.
