Common Unix Printing System

(Common Uncomfortable Pain Somewhere*)

*Yes we mean "there".

Over the years I have logged/wasted/learned for countless hours.

Basics

To restart local printer services you need.

sudo service cups restart

To restart the network broadcast(sharing) and browsing(using others) you need.

sudo service cups-browsed restart && sudo service cups restart

Next Level

Usually best to just start over by running three commands.
sudo apt-get install --reinstall cups cups-browsed cups-client cups-common cups-daemon cups-server-common

then:

sudo systemctl daemon-reload

You can check the statuses with

service cups status

service cups-browsed status
