I need help setting up printer?

I'm at work and I tried to print something from my MacBook Pro 2012 13'' model and I kept getting a notification saying the printer is not connected.

Since I had this problem two weeks ago I tried to tweak it a little and it worked fine but this time it did not work no matter how much I tweaked. So I tried to juist delete it and then add it again. But instead I accidentally reset the whole printing system including my default printer at home. Mad as I were, I went into System Preferences/Print and Scan. I see my work printer shown. I clicked on it and it was setting up then i get a pop up message saying something like the printer software is unavaible. From there I can't seem to do anything else.

So any suggestions to diagnose this problem?
