I am trying to send a print job from anywhere to a home network via its public IP address (I tried with and without a port number added ex. 40.230.2.2:9100), normal port number for RAW being 9100. I have a port forward setup on the router (which is a Verizon router/fiber modem) and still unable on my Windows 10 machine from outside the private network to "see" the printer for driver setup. I also created a port forward for SNMP to no success, yet when I forward port 80 to the printer I can pull its admin screen up from a browser. What am I missing to print from outside a private network? Also how might I setup printing through IPP, using the printer URI? enter image description here

Windows cant see your printer in the internet, you must show it...

  1. go to devices & printers on control panel
  2. select any printer
  3. select from window menu printer server properties
  4. go to ports tab
  5. add standard tcp port witch global IP (to router with port forwarding)
  6. install manually printer or connect to net with printer and install it ( disconnect from net with printer)
  7. go to printer properties
  8. select tab ports
  9. select added port, apply
  10. go to general tab and try print test page

The printer must have configured correct gateway

to IPP printer forward 631 port
