I am trying to print from Lightroom to the Pixma Pro 100 using the A3+ Paper size (13"x19")  In Lightroom, the page and printer setups are all correct (verified by Adobe's Tech support) and in the Print Preview area, everything looks great and ready to print.

Yet when I actually print the image to A3+ paper (and the image nearly fills the entire paper area) the resulting image is serverly cropped on the paper.  In fact is looks like it is cropping the image to 8.5x11, which obviously, only uses a portion of the 13x19 paper size.  It seems that Lighroom or the Canon Printer drivers are not respecting the selected paper size and defaulting to 8.5x11.

Here is a link to an image of what the print out looks like:

This does not happen when printing from Print Studio Pro, nor from Photoshop itself.

I've dealt with Adobe Tech support and Canon - both are point fingers at each other.  Meanwhile I am unable to print anything on larger paper sizes.

The Pixma Pro is the only printer connected and I've re-installed drivers and checked for updates.  Still the same.  At this point, any comments on the situation would be appreciated.

Thanks in advance!
