Excel 2007 : Printing to full page (on 4x6 index card)

Hello, I'm trying to print a sheet I've made on a 4x6 index card and use as much of the card as possible. I've made all the margins 0.00, chosen fit to page, and it still leaves almost an inch on the bottom and right side.

Any ideas on how to get it to actually fill the 4x6 card?
