[cups] How does CUPS find a driver?

I'm trying to get a Canon MG5550 printer working with Fedora/KDE.
(It works perfectly under Windows 10.)
I've downloaded and installed Canon's Linux driver (in rpm format),
and told CUPS to use the .ppd file that comes with the Canon software.
Unfortunately this does not work.

But what puzzles me is that I see nothing in the .ppd file
directing the printer to the Canon driver.
So how does CUPS know which driver to use?
