Lightroom printing issue vs Canon studio pro plugin

Hi everyone,

I have a PIXMA Pro 100 printer and have an iMac.  I have been getting strong magenta color casts in my prints.  In portraits it is showing as pinkish skin.  In landscape, the yellow/orange of the sunset is printing very very magenta. It's been driving me crazy.

Today I tried printing with the Canon printer plugin for Lightroom. I'm using the same .icc profile and same color rendering. It printed perfect - exactly as the screen. So, it seems like it isn't the printer or the ink

Does anyone have any thoughts or explanation as to what would cause Lightroom to print so magenta?

Thanks!
