Can I print 4"x6" and 5"x7" borderless prints on the Canon i9100 with paper I've trimmed to that exact size? Or do I need special "borderless" paper with some kind of larger than specified size and perferations? I'm thinking that I could get the 13" by 19" paper and pre cut it into 9 pieces of 4" by 6" at a lower cost than the 4" by 6" price, and wondering if this would work. Also does it slightly enlarge the prints to ensure that even if the paper isn't put in place in exactly the right place you don't get a slight white margin due to the paper misplacement? Thus meaning you need to avoid really tightly cropped photographs, or adjust for them. Finally, can you print more panoramic than 13" by 19" by having 13" by something longer than 19" paper, or does the driver cut it off at 19"? Thanks, Roland.
