Printing Graphics in Documents come out negative

We have several new workstations in our office with Windows XP Corp. edition
and part of the Office suite is Word 2002 sp2. When standard company
documents are printed that contain graphics (i.e. logos, etc.), this
graphics print negative of the display and print preview views. In other
words what should print as black is white and likewise, transparent white
background prints black. The documents still print fine on workstations
still running Windows 2000. Thought it might be a printer driver issue or
some preference in the Microsoft Office bundle.
