Add printers as standard (AD) user

In the images I have created so far, a standard user cannot add printers in System Preferences - Print & Fax module. I found this discussion about this problem: http://discussions.apple.com/thread.jspa?threadID=1373822&tstart=0 I have not testet this so yet, but what do you do to allow ordinary standard users (in my case logged in through AD) to add printers to their computer?
