Today i have tried to add one network printer on my Ubuntu 11.10 machine. When i am trying to go for adding printer it gives an saying that “FirewallD is not runining , Network detection needs services mdns,ipp,ipp-client, and samba enabled firewall“. Due to that i am not even able add the shared network printers.
It happens only in Gnome 3 dektop session not on Mate desktop session. Bug report is HERE, use the following command in terminal to install the printer.
