My fault entirely. The port number is 9100, not 631. I always make a
slip up along the way with things like this :). I am assuming the device
has an open port 9100; most HP printers do. You can check with

  nmap YOUR_PRINTER'S_IP_ADDRESS

Port 631 is for IPP and a protocol exchange is expected. netcat doesn't
use any protocols, apart from tcp/ip. It simply shovels the data over
the wire and hopes for the best. No wonder Margarita was confused.

Telling us that helped a lot.

It wasn't involved here but its best to keep it about for now, if it
suits you.
