I have a new printer Pixma TS8320. It won't print on 4"x8" photo paper. My old Canon Pixma MG5220 did just fine printing on the 4"x8" photo paper. Why isn't there a selection for printing on this size photo paper? If I click on custom, there is no way to tell the printer what I want.
I have been printing on 4"x8" photo paper for 8-9 years.
