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 – vipin8169 Oct 17 '12 at 8:26
Why is add button not enabled :/ – vipin8169 Oct 22 '12 at 5:36
maybe because the cups server isn't running, try browsing to localhost:631 – alex88 Oct 22 '12 at 8:34
and yes you are right, it is not running, i tried to install it as well but it failed – vipin8169 Oct 22 '12 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 – alex88 Oct 23 '12 at 9:00

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.

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 :/ – vipin8169 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 1 '12 at 22:38
well i don't remeber his name :P – vipin8169 Nov 2 '12 at 4:56
