I have a new Canon S800 printer. Great prints. However, I cannot find a way to get a full sized, 8.5 x 11 pix centered on the paper. I have tried making the image much larger than the paper, setting custom print sizes of up to 9.0 x 11.5; just don't work. I can't believe Canon would design a photo printer that would not have some setup wherein one can get an even border all around. Anyone figured this out?
