I have been using my Pixma Pro-100 for a few months generally printing to A3 and smaller with fine results. I am not sure I have printed A3 since upgrading to Mavericks so I should test that. I am now trying to print to A3+ 13"x19" and am now only getting a portion of the picture printed and in an incorrect orientation.
I downloaded a driver that said 10.9 on it but am thinking that Mavericks is not truly supported. Anyone else have this issue or workaround?
