Thanks for your help, I've printed my first 12x12 page! I hadn't gotten the 12x12 Epson paper when I posted but went out last night and found some. There was a disk for Panorama Maker included with the paper so with their instructions and your suggestions I managed to figure out what I was doing wrong.

I have another question though. Even though I checked the center box, the page wasn't actually centered. Is this the way it should print or will this be corrected when I resize my page? The page came out with about an 1/8" on the top and left and just under 1/2" on right and bottom. Is there a way to make it actually center on the page?

I like the idea of using decorative trimming and will be using that idea too.
