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 ?
