Trying to print a 10x13 pictures
I have a wide printer and I can print pictures up to 13x19. The problem is while using iPhoto 9.6.1 on my iMac 10.10.4 I'm trying to print a picture 10x13 but it came out 7.25x10.75. I keep wasting ink and paper. Why can't someone create a format that prints out custom size pictures just by typing in the dimensions.
iMac (21.5-inch, Mid 2014), OS X Yosemite (10.10.4)
