Stop Print Layout View from Shortening Pages
The Problem:
I'm using Print Layout view in Word 2003, and the page dimensions have gotten all weird. It's like someone lopped three-quarters of an inch off the top and bottom of the page.
The Solution:
Word hides unoccupied whitespace to help you see the rest of your document more clearly. To restore all the whitespace, choose Tools 
Options, click the View tab, and check the "White space between pages (Print view only)" box.
