After configuring the printer (which works on other Ubuntu 20.04 laptop) to be the default and trying to print a test page, nothing happens and the job is stuck.
$ lpstat -t
printer XEROX_B8045 disabled since lun. 04 janv. 2021 11:42:02 -
No destination host name supplied by cups-browsed for printer "XEROX_B8045", is cups-browsed running?
