OSX Mavericks and Pixma Pro-100

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?

Thanks,

Bruce

Printing from mavericks to pixma pro 100 and 9500II is no problem from either of our rMBPs. We are usually printing 11x14 images to fit off the shelf frame and mat packages

My resolution for large format printing was to export to iPhoto and print from there. Worked fine. That makes me think the issue is with LR and not Mavericks so much. I would like to have the granular control that I can get from LR but for 13-19 borderless if I export an image ready to go the results are excellent.

I was able to just print two 13x19 borderless prints from mavericks to pro-100 with no problem, printed from photoshop though.

Our Pro-1 should arrive next Friday to replace the 9500II. I will you know if we have any problems.

I also have Mavericks and Pixma Pro-100 and I have had zero problems.
