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 – Vipin Verma Oct 17 '12 at 08:26
  • Why is add button not enabled :/ – Vipin Verma Oct 22 '12 at 05:36
  • maybe because the cups server isn't running, try browsing to http://localhost:631/ – alex88 Oct 22 '12 at 08:34
  • and yes you are right, it is not running, i tried to install it as well but it failed – Vipin Verma Oct 22 '12 at 08:43
  • 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 – alex88 Oct 23 '12 at 09:00
  • it says: ops! Google Chrome could not connect to localhost:631 Suggestions: Try reloading: localhost:­631 – Vipin Verma Oct 23 '12 at 09:07
  • on terminal if you do sudo apt-get install cups what you get? – alex88 Oct 23 '12 at 12:42
  • i get>> Package cups is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: cups-filters

    E: Package 'cups' has no installation candidate

     – Vipin Verma Oct 25 '12 at 05:17
  • these packages are already installed>> cups-bsd , cups-client , cups-common , cups-filters , cups-pk-helper , cups-ppdc – Vipin Verma Oct 25 '12 at 10:33

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.

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? – fossfreedom Oct 30 '12 at 11:04
  • well, i was having chat conversation on stackexchange network with someone regarding an issue on my system and he asked me to do that :/ – Vipin Verma Oct 30 '12 at 11:07

    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? – Paul Hänsch Nov 01 '12 at 22:38
  • well i don't remeber his name :P – Vipin Verma Nov 02 '12 at 04:56
