I'm trying to print to two networked printers on an internal Windows Server 2003 LAN from the outside internet. Both printers (HP 4050 and Konica BizHub 751) print to port 9100.
I can set the printer port on my local installation of the printer to the Public IP of the internal LAN. I can port forward port 9100 on the internet router to the internal IP address of ONE of the printers on the internal LAN, and printing works fine. How can I print to the second printer that also uses port 9100, when I can only port forward 9100 to one IP address?
I assume I have to tell the physical printer to communicate on a port other that 9100? If this is correct how do I do that?
