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 Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1931612 Title: Print dialog box shows same printer twice Status in cups package in Ubuntu: Confirmed Bug description: I have set up a single HP printer which is attached to my network. The setup process went smoothly, and when I open the Printers system setup panel, I see only my printer there. However, when I print from an application, and that application uses the system print dialog box, my printer appears twice. One entry, matching the name correctly, works fine. The other, which a slightly changed name, does not work at all. See attached screenshot. Applications that have their own print dialog box do not have this problem. For example, Firefox shows only my printer once. Same thing with Libre Office.
