CUPS and Firewall

Running Suse 12.2 with KDE 4.8.5, Epson Stylus SX400 (NOT a wifi printer)

Is there a way of allowing CUPS port 631 in the firewall settings? I'm trying to share my printer via the LAN so I can print from my tablet, and although the printer is visible in the tablet's printer app, it is impossible to print from it. Most error messages seem to indicate, that it could be a firewall problem. (see tab's screenshots)





For example, this is the error I get when I try to set up the printer this way:

Quote:

ping: unknown host cellar
Testing share 'Stylus-SX400' on 'Workgroup/cellar':
protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE
Share 'Stylus-SX400' on 'Workgroup/cellar' does not accept print jobs (share may not exist?)
Host 'cellar' unreachable (network issue or wrong host or firewall active?)
And if I try it that way 14.4.2.1 (14.4), I get this message:

Quote:

The server '168.192.0.6' is not accessible via port 631 (IPP/CUPS).
The server '168.192.0.6' does not respond to a 'ping' in the network.
The server name '168.192.0.6' is not known in the network.

If I got to 192.168.0.6 (being my machine) port 631 manually, it says forbidden.

When I go to firewall settings for internal zone I can't see CUPS. I can't add it manually either because everything is greyed out.
To be honest I don't know much about LANs etc and this is the first time I have tried to share a printer, also I'm not trying to share the printer with a windows machine, but I can't seem to find any tuts on how to just share it with an Android.

Any help is greatly appreciated.
