Printing rasterbator images

[Brian Wallen]

I've got my printer working with cups, but when I go to print something from rasterbator, it cuts off the edges. In case you don't know what rasterbator is, it takes a picture and enlarges it to fit multiple sheets of paper, then you print each page out and put them together. The picture goes to the very end of every page. However, when my printer prints the individual pages, it leaves a white border around the outside, cutting off some of the picture.  So if anyone knows how I can tell cups to print to the edges of the page, please let me know. I'm using an HP photosmart 7350 with the hpoj drivers if it makes a difference.
