I had added my user to the group
lp, but still got this error when trying to list printers.
$ lpinfo -v lpinfo: Forbidden
I found that the key was in this post on the Arch Linux Forums.
sudo groupadd printadmin sudo usermod -a -G printadmin $USER
Then I had to edit
/etc/cups/cups-files.conf and change the following.
SystemGroup sys root
SystemGroup printadmin root
Once I did that and rebooted, I was able to see output from
lpinfo -v without needing root access.
$ lpinfo -v network http network beh network lpd network socket network ipp network ipps network https direct hp:/usb/Photosmart_D110_series?serial=CN0CAG436D05N9 direct usb://HP/Photosmart%20D110%20series?serial=CN0CAG436D05N9&interface=1 direct hpfax
At this point, I could use the
Print Settings in
MATE to add my printer.
