Trying to set up a new Canon Pro 300 printer and I seem to be completely lost and stuck.Using MacOS High Sierra 10.13.6 and everything is now connected but the printer will not go past the date setting and the computer says the printer is not connect...
Have washed the print head until I got an Error code 200 , then purchased a reconditioned print head and have basically the same thing with the blacks and PM PC printing and no colors any suggestions would help 
How can I get custom border sizes using Canon Pro9500 MarkII printer.? I find a help page but can't find the box to adjust.
