My HP ePrint printer is behind an ADSL router with firewall/NAT functionality. The printer has an internal ip address. 

Incoming connections from the internet are by default denied unless I open specific ports and protocols on the firewall and do natting to the internal network. What do I need to to open to allow HP to send print jobs to my HP printer at home?

You will need to enable the following 2 ports:

 

5222 (for XMPP protocol)

443 (for HTTPS protocol)

(Although I am an HP employee, I am speaking for myself and not for HP.)

This setup works for me on a port-based firewalled NAT router with all inbound/outbound TCP/UDP ports blocked from 1 to 65535 except those enabled out of necessity like DNS (UDP/TCP port 53). I added TCP port 5223 (XMPP over SSL) outbound only to the NAT firewall. TCP port 443 (HTTPS) outbound was already enabled. No UDP ports. No inbound. No need to do NAT port forwarding. Port 5222 (XMPP) also works for me but it's unencrypted, I believe.

 

It takes several minutes for the ePrint service to get established but it does eventually work. I think the printer tries to connect to the ePrint service on port 5222 first and when that fails it tries 5223 so it takes a little more time to get connected. But, that's just a guess.

 

See http://xmpp.org/rfcs/rfc3920.html if you care to know more about XMPP.
