I am trying to set-up a network printer on my system.
Navigated to System Setting>>Printing and viola the Add button out there is disabled.
When i troubleshooted using Help it said that the CUPS print spooler does not appear to be running. To correct this, choose System->Administration->Services from the main menu and look for 'cups' service.
Please tell me what to do in order to add a printer
Try to open a terminal (or alt-f2 to display command execution prompt) and run
sudo system-config-printer
and check if you can add a printer from there.
Open a web browser and navigate to http://localhost:631. This is the real interface to your printing system. If you want to do anything fancy, do it here. You are eliminating a lot of potential error stemming from bugs and flaws in the gnome printer dialog. Mostly the gnome dialog is just oversimplifying on some advanced functions.
If you don't see a website on localhost:631 your cups daemon (the printing system) is not running at all. Make sure it is installed.
sudo apt-get install cups
#my CUPS was not installed after upgrading to 18.04, after i did this printers showed right up just had to close and reopen the printer app
Modify the contents of /etc/environment file from
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
http_proxy="http://111.125.139.199:8105/"
https_proxy="https://111.125.139.199:0/"
ftp_proxy="ftp://111.125.139.199:24/"
socks_proxy="socks://111.125.139.199:0/"
to
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
