I am assuming you are printing on Epsons 12x12 paper.

I have an Epson 2200 and what I did (in PSE) was set up a User Defined paper size (last option in paper sizes) as 1200x1200 (0.01inch) and named it scrapbook page. In the advanced options set your printer to minimize margins. It tells you that it may reduce the quality, but I haven't noticed the difference. Then when I go to print I resize my page to 11.667 x 11.667 inches. In fact this is the size I create all my pages in right now.

You will have a border of white around your page because there is no way right now to do borderless on the 12x12, but most of the time it doesn't matter to me. And if you must have it borderless then you will have to use the 13x19 paper and trim. But I'm not sure if that paper is able to print on both sides since it doesn't specifically state it like the 12x12.

Hope that helps, its my first time posting here on the site. (Been here for only a couple of weeks and loving it!)
