Same issue on my computes + NAS, with Ubuntu 20.04. I applied the same settings that in the case of 16.04. Result: 20.04 - nothing is printed. 16.04 - print without any question or issue.

Normally, system-config-printer can found it with search functionality. The expected result is: smb://freebox/Brother%20DCP-J752DW But in 20.04 I can't because System-config-printer ask for a password to access workgroup. But there is NO password! The printer is shared without identification needed. I still have ubuntu16.04 on same machine and I am forced to print with it. I give the output of system-config-printer --debug file with 16.04 if you want to compare with 20.04. I have installed python3-smbc (1.0.15.6-2build2) to have the search functionality (software-center proposed to install it but can't!). Then I have allowed samba with sudo ufw allow samba because system-config-printer ask it to try to access printer. :~$ lsb_release -rd Description: Ubuntu 20.04.1 LTS Release: 20.04 :~$ apt-cache policy system-config-printer system-config-printer: Installé : 1.5.12-0ubuntu1 Candidat : 1.5.12-0ubuntu1 Table de version : *** 1.5.12-0ubuntu1 500 500 http://fr.archive.ubuntu.com/ubuntu focal/main amd64 Packages 500 http://fr.archive.ubuntu.com/ubuntu focal/main i386 Packages 100 /var/lib/dpkg/status Printer: brother DCP-j752DW, cups drivers from brother site.
