George might have the final answer, maybe your model will only work via a USP connection if using the brlaser option. But, I checked my virtual machine to see how it is connecting to the printer... Brother_DCP-L2550DW_series Brother_DCP-L2550DW_series (Idle, Accepting Jobs, Not Shared) Description: Brother DCP-L2550DW series Location: Driver: Brother DCP-L2550DW series, using brlaser v6 (grayscale, 2-sided printing) Connection: dnssd://Brother%20DCP-L2550DW%20series._pdl-datastream._tcp.local/?uuid=e3248000-80ce-11db-8000-3c2af4d12445 Defaults: job-sheets=none, none media=na_letter_8.5x11in sides=two-sided-long-edge So it does seem to be using dnssd. This is a pretty generic F36 XFCE install so I did not do much to get that working, mostly just needed to start cups. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
