can anyone tell me how I can print 5"x7" borderless prints on my canon s900. It only does 4x6 borderless? Is there a software download or something I can use. As far as I know canon papers are the only ones that work right on the s900. I know I could use 8"x11.5" and print 2 5x7 on that but then I would have to trim them and I was hoping to just pop in a canon 5x7 sheet and print it borderless
