Now we have cleaned up the mess of your use of "systemctl mask ..." and of your attempt to replace your system's CUPS by the Snap of CUPS.
Next step is to investigate to find out what the actual bug is. In the print dialog of your evince there are two entries. The second entry, "BROTHER_MFC_L2710DN_series", got automatically created as CUPS is able to create a temporary queue when you send a job to this queue name. The first entry, "Brother-Printer" looks like that you have manually created it. What exactly did you do to obtain it? And are you able to print on both entries? In case you are able to print on both print queue entries which the dialog is showing, there seems to be no bug with the printing functionality of GNOME applications but only a bug of the "Printers" part of the GNOME Control Center. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/2083530 Title: gnome-control-center not able to add printer or make settings Status in cups package in Ubuntu: Incomplete Status in gnome-control-center package in Ubuntu: Incomplete Bug description: don't know why, but i'm no more able to add a printer or make specific settings and also unable to remove it.
