I had a similar thing happen to me yesterday - someone brought me a copy of a
template they printed - a "square" appeared in the middle of the document the
first time she printed it - the second time she printed the document - it
appeared in a different place - the third time she printed it - it was gone.
Also, on a completely different document the "square" showed up again but had
the words "formtext" after it. When I unprotected and looked at the document
there was nothing out of the ordinary. You can't see these weird things when
you view the document online, they only show up - and not every time - when
you print. This leads me to believe that it is a print driver issue. I'm
having her print to a different printer for a while to rule this out.
