Ubuntu 18.04 LTS -- Printing Service Not Available
Solution 1:
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
