I'm trying to setup a printer with knoppix live CD 5.1.1

First I got an error occured while retrieving the list of available backends ...

So I opened the root shell and typed cupsd - that got rid of my error and fixed that problem. But now I'm trying to add a printer and the add a local printer is greyed out. I've done a lot of google searching but can't seem to find a solution to the problem.

How can I get access to add a local printer? Can someone please walk me through.
