Does Print Preview show a blank document? If the document consists entirely
of wrapped graphics and text boxes, make sure that "Drawing objects" is
checked on the Print tab of Tools | Options.
If that's not the issue, and if this is a small-format document, it could be
that the printer is printing somewhere other than where the paper is. Try
printing a full sheet to see where Word and the printer think the document
is. If you can't work out a way to feed the paper where the printer wants to
print it, then you'll need to use the full-sheet paper size and make up the
difference with margin adjustments.
