MS Publisher 2000 – 4 sheets per page

How do you prevent an outline from printing around each page when you have an 81/2 by 11 page and choose From File, Print Setup, Properties, 4 sheets per page. When printed it automatically resizes the information to fit in 4 pages on a single sheet of paper, but it puts an outline around each of the 4 pages on the sheet. I’m printing this publication and the lines look very bad.
