Trying to print an emailed airline itinerary, but only get the rest of the Yahoo page. Any suggestions?

Have tried using the print tab and also the print command in the right click window (makes no difference). The last page with just text prints fine, but the boxed-in itinerary seems to be transparent to the printer. Using Windows 7, Yahoo beta, a one year old HP computer and an older HP printer, that otherwise seems to work fine.
