However my Mint 14 laptop cannot find the printer, when I try to add a network printer I get the following message;
FirewallD is not running. Network printer detection needs services mdns, ipp, ipp-client and samba-client enabled on firewall.
I used to be able to access my GoFlex through an IP address - http://goflex_home or http://<IP address>, but now this does not work, I cannot successfully add an address to the Add Printer search box...
I don't know what this means or how to remedy this!!
