In case you are accessing a shared USB printer on a Windows machine I am sharing another workaround: https://askubuntu.com/questions/1039052/always-prompts-for-username-and-password-when-printing Spin up the built in LPD print server via Windows additional features and map the printer on Ubuntu through lpd:// instead of smb://
By the way the "This bug was fixed in the package system-config-printer - 1.5.12-0ubuntu1" did not fix the issue. I am currently on 1.5.12-0ubuntu1.1 and the bug is still there. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1849859 Title: smb printing fails Status in cups package in Ubuntu: Confirmed Status in samba package in Ubuntu: Confirmed Status in system-config-printer package in Ubuntu: Fix Released Bug description: when I connect to smb server (nas) permanently appears "Error while getting peer-to-peer dbus connection: Operation was cancelled" The printer at this NAS doesn't work too.
