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 printerFollowing is the ScreenShot of what i was doing

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.

  • No, I can't. The same window opens up which is shown in the screenshot above Oct 17, 2012 at 8:26
  • Why is add button not enabled :/ Oct 22, 2012 at 5:36
  • maybe because the cups server isn't running, try browsing to localhost:631

  • and yes you are right, it is not running, i tried to install it as well but it failed Oct 22, 2012 at 8:43
  • I mean if you paste that address into your browser shows anything? Because that's the cups service port, just to check if it's running

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"

    very unusual - maybe you can explain why you had a proxy setup - surely that would affect other network related stuff by removing the proxy?

    well yeah, this obviously was the reason, since the printer setup utilities use http connections to localhost to configure the printing system, and you where redirecting all http traffic over a server in ... India... btw. are you aware of that? If not, who asked you to do this? Nov 1, 2012 at 22:38
  • well i don't remeber his name :P Nov 2, 2012 at 4:56
