Printing a layout in IWP Help!

[SpadeFlush]

I have a layout that is made to print out on 8.5X11. It prints out just fine from FMP11. When I use IWP and print it out I get different results. The problem is the size of the layout changes from browser to browser, so in some browsers it will reduce to a smaller size and in some browsers it will print to 2 pages with part on 1 page and another on a second page. I know about margins and printer settings but have had no luck getting the same printed results from different browsers. Any suggestion or Tips?

Thank you
