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 is already the newest version (2.2.7-1ubuntu2.1).

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.
