[ale] finding printer connected to wireless router

[Jim Philips]

I just bought a Belkin N600 wireless router. It allows you to connect
your printer to the router via USB cable. I can print to this printer
in Windows. But in Linux, I have one problem after another. This is in
Linux Mint 12. If I try CUPS, it never sees a printer at the IP
address of the router. If I create the printer anyway and use the IP
address, plus port, like so: 192.168.2.1:9100. The printer appears to
get installed. But if I try to print anything, CUPS just says "the
printer is busy". If I try using the standard printer setup tools in
Gnome, I'm immediately greeted by this message:

"FirewallD is not running..."

And a notice about needing mdns, ipp, ipp-client and samba-client
enabled on the firewall. Extensive googling hasn't found anybody who
got past this issue. I don't even know if it's  *the* issue preventing
my printer from being seen on the network. But all available tools
fail to show anything connected to the router. I don't know where to
turn. Please let me know if fellow ALErs have figures this out before.
