right print margin larger than specified in exported file

Hi all –

When I export a file into Word.doc for printing, the right margin (which is set at 1" in my document window) is larger than it should be, somewhere between 1.5 inches and 1.75. I can adjust the look of that right margin by changing it to .5 inch in document settings (in WORD), and it will look ok when it prints, but it seems wrong. And what will happen if I send it off to someone else to view on their machine?

Is there a way to address this?
