> Also beware that if you're doing this on a radio network, I don't think netcat can encrypt the traffic. So don't be printing your credit card statements this way. Of course netcat does not encrypt anything. But if your printer accepts encrypted traffic you can send that over netcat. The question is what encryptions do the printers support? What protocol (stack) CUPS uses in the end? I have never heard that a printer certificate has expired, so my first guess would be it's all in cleartext.
