I just got a new firewall program and now it blocks access to the printer. I remember back when I installed it I had a different firewall that did the same thing, and the install wizard told me to unblock a certain port. Now I can't find which port number that is! If you know which port the printer uses, please reply!

These are the ports that you need to unblock in order for your printer to work:
UDP 427 inbound
TCP 139 outbound
UDP 427 outbound
TCP 9220 outbound
UDP 161 outbound
TCP 9500 outbound
UDP 139 outbound
TCP 9290 outbound
And these are the softwares that should be added to the exceptions list of your firewall:
Open the C:\program files\HP\digital imaging\bin directory, and then locate the following files:
hpiscnapp.exe (for HP software v10.0 or later)
hpqscnvw.exe (for HP software v9.0 or earlier)

Try to turn off your computer, printer and your router. Wait for like a minute or two. Turn on your router first, and then your printer, and lastly your computer. Give at least a minute of interval to turn on each devices.
