I'm running High Sierra. I'm trying to print from Photos to my Canon MG7720. I can't get the photos to center on the paper. Whether I'm using 4x6, 5x7 or larger, What ever option on choose on the print dialog, there is always a wider border on one edge and often on top or bottom. I thought that if I had 4x6 photo paper and selected 4x6 from the print dialog, I'd get an even border around the edge of the photo. But one side is much larger than the other. Anyone know how to fix this?
