What kind of printer are you using?
A possible workaround would be to export to PDF from Word, and then print the PDF from Acrobat.
This is the second recent problem we've had reported in which things look fine on screen but don't print properly. It is very strange to me, because I'm used to printers simply reproducing what you see on screen.
