Unable to Add Printer in Fedora 35

[Richard Kimberly Heck]

I'm trying to add my Brother DL-5450DN printer in a new installation of 
Fedora 35. No matter what I do, I get this error:

Unable to create PPD file: Could not poll sufficient capability info 
from the printer

It's discovered just fine, and I've not had anything like this problem 
previously. Any suggestions?

Possibly a connection problem. Are you using the correct Brother RPM
package for your model?

I had problems adding my Pantum printer, because Fedora was trying to use ipps:// URL's rather than the advertised ipp://. This resulted in the IP stack on the printer crashing (yay for crappy vendor firmware!), and any subsequent operations on the printer failing until it was manually rebooted.

I ended up manually modifying the URLs to ipp:// and everything worked perfectly after that.
