So the Canon CP900 can only print max 4x6?
It is marketed as a dedicated 4x6 photo printer. I would be very surprised if it could print any other sizes.
I was under the impression that it could print larger sizes, 6x8 or so, but it appears that the only paper/ink combos that Canon sells do max 4x6. What gives?
What gives is you've failed to do your homework
