Hi torino71,
Welcome to the HP Support Forums! I see you would like to know which proxy settings to set for your HP Photosmart 7520. I was able to find a great thread from a fellow Community member windrunner123, see below:
In some network setup, proxy settings may need to be configured on the printer to enable connection to the Internet.
1. Make sure the printer is on a network and must have an IP address assigned by a Network Router or a DHCP server. Alternatively, you may also configure the printer to use a static IP address.  Check and retrieve the IP address of the printer from the Home Screen menu selection: Network -> View Network Summary -> View Wired (or View Wireless)  or Setup -> Network > View Network Summary (depending on printer model)
2. In a web browser on your computer, type the IP address or hostname that has been assigned to your printer.
3. Go to the Network Tab > Proxy Settings and enter the proxy settings into the fields and click Apply button.  You may have to check with your ISP or IT Administrator for the correct Proxy Setting.
As well as the port settings below you will want your router company to make sure that multicasting is enabled, bonjour protocol needs to be enabled, make sure that mac filtering is disabled, and have them check if there are any firmware updates for the router, and check firewalls on the router to make sure not blocking the communication
The following ports are also used by your HP device and might need to be opened on your firewall configuration
Incoming ports (UDP) are destination ports on the computer while outgoing ports (TCP) are destination ports on the HP device:
Incoming (UDP) ports
137, 138, 161, 427
Outgoing (TCP) ports
137, 139, 427, 9100, 9220, 9500
The ports are used for the following functions:
Printing
UDP ports 427, 137 161
TCP port 9100
Photo card upload
UDP ports 137 138 427
TCP 139

TCP 9220, 9500
Faxing

TCP port 9220

I hope this helps! If you have any more questions please let me know.
