I also see this in Ubuntu 20.04 Gnome. I have installed my Brother HL-L3270CDW printer using the official driver, for all features to be available:
https://support.brother.com/g/b/producttop.aspx?c=us&lang=en&prod=hll3270cdw_us_eu_as Now, if I open the "Printers" dialogue, the manually installed Brother printer instance is shown as "Brother HL-L3270CDW CUPS", as well as a doublet called "Brother Brother HL-L3270CDW series[en]". If I remove the automatically added printer, it immediately re-appears. See also these two issues, where many Ubuntu 20.04 users see an already installed printer twice, so it seems quite a few users are affected by this: https://askubuntu.com/questions/996020/cannot-stop-network-printers-are-being-automatically-added https://askubuntu.com/questions/345083/how-do-i-disable-automatic-remote-printer-installation Things I tried, suggested on pages above: #1, With this, Libreoffice Write stalls for 30-40 seconds: enable-dbus=no #2 This didn't make any difference: sudo systemctl stop cups-browsed sudo systemctl disable cups-browsed Shows same printer twice: Printers (via Ubuntu GUI) Image Viewer (default, with Ubuntu) LibreOffice Write Shows only the correct printer: Firefox (and other browsers) Like Timur Tabi (timur-tabi) wrote on 2021-06-14: > The GTK developers tell me that this is fixed in the latest version of libgtk. How do I upgrade libgtk to the latest version on Ubuntu 20.04? Is there a way I can pull in an update for just this package from a newer version of Ubuntu, without breaking everything else? Is there a way we can try this latest version of libgtk on Ubuntu 20.04? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931612 Title: Print dialog box shows same printer twice To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1931612/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
