I used the standard Fedora gui interface to find the printer on my
network, choose IPP, and follow all the prompts to find the printer make
and model, and said yes to the recommended driver, screenshot here:

My understanding was the fedora gui knows how to download any blobs
necessary for known printers in the database.

Am I missing something?
