Ethernet Printer behind router

Hi all

I have a linksys wireless router and a Hp 2420 ethernet printer. I have
the printer set with a private ip address behind the router. I want to
use it from the outside world.

What port do I have to forward?

I have managed to discover the printer and setting it up. However when
every thing seems to work well the job is not printed.

All my PC are running windows.

Any help is welcomed.


P.S.: I don't know if this is the correct group. If not, please refer me
to another one.

Microsoft's LPR uses only ports 721-731 by default

but I don't see how you can print from the outside. How are you going
to tell a internet based print job to print to a private ip address?
The print job would have to know the public ip address and then the
private ip address to get to the printer.

Probably the best way to do this, IF you have a Win2000+
HTTP server at your DMZ (or mapped from your NAT)
is to use HTTP printing.

Let the users use HTTP to the Web server which will find
the printer FOR THEM.

This also respects the permissions so they will need to
authenticate unless you wish the world to exhaust your
paper tray.

By using the port forwarding feature of the router.

But I still need the ports ;)

Unless the printer has it's own security I am suggesting
you do it through HTTP printer.

Then you forward port 80 to the HTTP server which
will do the printing to the actual print device.
