Ubuntu – Ubuntu 18.04 LTS — Printing Service Not Available


My printer no longer shows up in my Settings -> Devices GUI menu. Instead it says "Sorry! The system printing service doesn't seem to be available."

I tried searching the 'net for ideas and I ran these terminal commands with the following output:

john@john-max:~$ sudo service cups restart
john@john-max:~$ systemctl status cups

● cups.service - CUPS Scheduler

cups is already the newest version (2.2.7-1ubuntu2.1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

One thing which might matter: I recently opened Startup Applications and accidentally over-deleted some things there and don't know what they were. Maybe something for the printer service was in there?

I also tried re-installing my printer drivers for my printer but it just says already installed.

On Ubutnu Software as well as by running

sudo apt-get update && sudo apt-get upgrade

I show my software as all up to date.

I'm fairly novice so if you tell me what to do, if possible, please give me the actual terminal command.

I had same problem. Config file is incorrectly located. Follow directions as per this link. https://ubuntu-mate.community/t/cups-service-stopped-um-18-04/17381

There is a default configuration file which should be installed in /usr/share/cups/cupsd.conf.default so I ran:

sudo cp /usr/share/cups/cupsd.conf.default /etc/cups/cupsd.conf
sudo service cups restart
