Just an update.
I thought I would try the new Driver printing with Lightroom and Photoshop and comparing those prints to Canon PP&L.
I remember there being a problem printing out of Lightroom with the 16-Bit box checked, so I tested that too.
To my eye, there is no difference between the three applications and having the 16 Bit box checked makes no difference either.
For pure convenience’ sake, it looks like I will go back to printing out of Lightroom at 16Bit….
Also, with the old drivers, every time I exited the driver and then opened it again the “Media Type” had always defaulted back to “Plain Paper” …not anymore, it stays where I left it!
