How to change TCP/IP port number on a HP CM2320 printer ?

Hi,

I have a HP CM2320 printer, and would like to be able to print to it from the internet.
I have set up Port Forwarding of Port 9100 against an other printer, so I can't use the same port.
My router is a Technicolor TG582N, I tried to setup port Translation from outside port 9102 to inside port 9100 pointing to this printer, but without any luck.

My question would be:
Could I change by any means the port number on the HP CM2320 printer so that it accepts printing on port 9101 or 9102 instead of 9100?

Thank you,
Elemer
