Large margin at page bottom is not correctable

When I view pages in print layout in Word 2002, the margins look even all
around -- just like I want them. But when the pages print out there is a
noticably larger margin on the right and at the bottom.

I've made sure that the printer's default is A4, and I've selected A4 as the
proper size paper for the document. I've turned off letter/A4 resizing. I've
reveiwed the size and placement of the footnote box.

What else do you think it might be? Any help is appreciated.
