Print Studio Pro not finding PRO-100 printer

[mrswitters]

I'm on an iMac Pro, running Big Sur. I just installed Print Studio Pro. In Lightroom, when I went to File > Plug-In Extras > Canon Professional Print & Layout, I get the following error message:

When I click "Find Printer", no printer appears in the selection window.

I have the driver installed properly:

I don't believe PP&L is compatible with the Pro-100. 

And there is a bug with Big Sur 11.6 and PSP. 

I print directly from LrC to my Pro-100. I never found PSP useful.
