In the past, I imported 8.5 x 11 eps files (generated from the music notation
program Finale) into an 11 x 17 Word document, which looked fine and printed
fine. Now, both these files and new ones i generate, come with a vertical
band of the right page deleted and the page prints that way too (with a white
broad band on the right).

Why is it happening and how do I fix it?

I am using a 2001 version of Word that came in Office.
