I am encountering the same problem. While using Ubuntu 12.04, I was able to install the network printer using Samba and it worked all the time. Last month I upgraded to Ubuntu 12.1. The upgrade went without any hitch. Last week I wanted to print a document and it would not print. It was being held in queue. So I opened Sytem settings and clicked on Printer. It showed there was no printer installed. I am using HP Officejet 4500-g510 g-m printer attached to a Windows XP computer. So I tried to add the network printer and it gave me "FirewallD is not running. Network printer detection needs services mdns, Ipp, Ipp-client and Samba-client enabled on firewall".
