Which app ports required for basic and/or advanced printing within Router?

[Tropiocolotes81]

Is it common for wireless printing to open some application ports in the NAT firewall of a Router, for wireless communication to work properly?

This was not mentioned during the software installion, but I found out about this after searching the HP support site about WiFi printing problems.

I found out that my Router was blocking traffic over TCP/UDP port #4129 (id: nuauth), and therefore declined all print jobs AND ePrint to function properly..?

Also, I needed to add rules for TCP/UDP ports for 9100 and 9220...
I guess the 9100 (hp-pdl-datastr) is needed for the actual communication?

My Router is a Ubee EVW321B.

Nice user-friendly interface, but maybe somewhat over protective..?

I would like to read if other users did assign some ports for the PS 5522 to work properly over a WiFi connection?

The document here has information on the port settings for the Photosmart 5520 printer.  Your router was not listed, but it suggested the following for unlisted cases:

1. If your firewall software is not listed in the table, manually unblock the ports used by the printer.
   1. Open your firewall software, then locate the configuration settings.

       NOTE:

      Only change the settings in your local area (home) network. Before proceeding, contact the firewall vendor for additional information on how to change these settings.

   2. Set your firewall to unblock the following port range:
      • UDP port range 1000-65535

       NOTE:

      You do not need to specify each port individually for this port range. Set one port rule for the entire range of ports.

   3. Set your firewall to unblock the following individual ports:
      • TCP port 80
      • TCP port 443
      • TCP port 8080
      • TCP port 9220
      • TCP port 9500

       NOTE:

      Set one port rule for all these individual TCP ports.

Thank you Bob,

The document describes it, so let us assume the relevance of the settings. 😉

My printer works quite well, sometimes halting for a brief moment but that is more because of interference I guess.
