A family of Microsoft word processing software products for creating web, email, and print documents.
I believe you're dealing with 2 separate issues...
The printing issue is most likely due to a Preference setting. Text Boxes are graphic objects, so in order for them to be printed go to Word> Preferences - Print, then check the box for Drawing Objects. You may also want to check the one for Print background colors & images, depending on whether there is any graphic content in the Header/Footer.
That should have no effect on viewing the document on screen for you or anyone else, though. My impression is that this is a separate issue, but it's difficult to determine without details pertaining to the systems having a problem displaying the content. Generally, it is symptomatic of font problems but also could be due to software version and/or update level as well as other contributing factors. If the document displays correctly on 1 Mac the problem is most likely local to those which are unable to display it. There really isn't much you can do to control how a Word document displays on another user's computer.
Quite frankly, unless the recipients are intended to edit/revise the document I wouldn't send them a Word document file in the first place. It would be more efficacious, practical & secure to generate a PDF & forward copies of that.
