Public bug reported:

Hello,

I have 2 computers(one laptop and one desktop) which have a dual boot
Windows / Ubuntu. My printer (Xerox WorkCentre 6015B) is plugged on a
USB port from my modem on which my computers are connected using Wi-Fi.

Since the upgrade of Ubuntu to version 19.10, I cannot print. On both
computers I get the same message : [The printer] requires authentication
/ credentials required in order to print.

With Ubuntu 19.04, I had absolutely no problem. I tried with a live USB
with Ubuntu 19.04, there is no problem, the printer works. With a Ubuntu
live 19.10, it doesn't work.

If I plug the printer directly on a USB port on my computer, I get the
same error message : [The printer] requires authentication / credentials
required in order to print.

It's the same behaviour on both computers, no I guess it must be a bug.
Anyway I don't know which authentication I could do, with which ID and
password ?

Thank you very much
