I had an issue connecting a printer in gnome settings.

After ensuring that the user was in the correct group and the service was started, I was getting the message “Failed to add new printer.”

It should be noted that adding a printer from worked fine so I suspected the cause of the issue was a missing dependency for Gnome’s printer settings.

Ensure cups is started

Ensure that cups is running and starting at startup

sudo systemctl start cups
sudo systemctl enable cups

Note that the service used to be called org.cups.cupsd.service so it may have stopped working due to the name change

Ensure user in the correct group

Ensure that you are in the lp group

sudo usermod -a -G lp $USER

This will require you to log out and log in again

Confirm with

groups

Try adding a printer from the web gui

Try adding a printer from . If it works, the issue is likely not cups related.

Install system-config-printer

If trying to use gnome’s printer settings, adding a printer may result in the message “Failed to add new printer”.

Adding a printer in the web ui worked without issue so the issue wasn’t cups.

Adding the following fixed the issue

sudo pacman -S system-config-printer
