Anyone used an HP JetDirect 510X (3-port external print server) with
Netcat?

The HP manual on the 510x lists ports 9100, 9101, and 9102
as "telnet" ports and specifies:

> ? Use the following Telnet command:
> telnet <IP address> <port>
> where <IP address> is the IP address assigned to the
> HP Jetdirect print server and <port> is 9100. (HP Jetdirect
> data port 9101 or 9102 can also be used for ports 2 or 3
> respectively, of a Jetdirect multiport external print server.)
> ? In the Telnet session, type in data and press Enter.
> ? The data should print to the printer (a manual form feed may
> be required).

I have used 170x single port models in the past with Netcat but
I don't remember if the manual suggested telnet or described
9100 as "Direct Port Printing."

I'd like to avoid buying another piece of hardware and having to
return it if it fails to work with Netcat.
