Yes. On the client OS's you should see incoming packets of about 189 bytes
every 30 secs. gkrellm shows these, or if you run wireshark, you should see
these cups broadcasts from the machine with the printer attached.
A 5 minute wireshark capture on the client box shows no cups packets
on the wire. (Cisco-Li_7a:5e:07 is aku the router, AsustekC_e9:c9:c0
is diningroom and Giga-Byt_27:c0:ff is haggis - also the print server.)

Running as user "root" and group "root". This could be dangerous.
