On the latest version of Gnome Manjaro, 20.2. Printer used to work on 20.1 and now cannot be added. The printer is on the same network as the computer, and shows up when searching.
Thanks for the reply. Using hp-setup -iax and selecting option 1 (net, Network/Ethernet/Wireless (direct connection or JetDirect)), gave the following error
error: No device selected/specified or that supports this functionality.
I get the same error when using the GUI HP app hplip.
I have the same error message in Gnome settings, but with a Brother MFC printer. Have you tried to add your printer through the web interface on localhost:631?
