Ubuntu autodetected network printer prints garbage (Xerox WorkCentre 3125)

[Norse]

Guessing at the filters package based on the routing info on the Apple CUPS bug filing page

I have a Xerox WorkCentre 3125, and it works fine with the other machines in the house and has worked fine on prior versions of Ubuntu.

On Ubuntu 20, it's autodetected and installed... but if I try to print anything, a few hundred pages of garbage fly out of the printer.

It turns out that this is a driverless setup over IP (Wifi), and it defaults to compressed transmission.

If I set job options to add "compressed" with value "none" in the additional printer options, I can at least get most things printed (there are some other bugs preventing images from printing)
