Can Not find Network Printer

[VA3NAZ]

My network printer disappeared after upgrading to Ubuntu 12.10 from 12.04. When I try to add anetwork printer, it gives me a message: "FirewallD is not running. Network Printer Detection needs. mdns, IPP, Ipp-client and Samba-client enabled on Firewall.

Also my computer/yser name has disappeared from the menu bar on top right corner.
