I need to configure Norton 360 firewall to allow hp Officejet scanning

I am trying to understand how to configure the N360 Firewall to not block communication with my HP Officejet 6700 wireless printer during scanning. I am running Win 10, latest Nov. 1511 build. I lose communication at random times. Do I need to create Traffic Rules? The printer IP Address is Full Trust; it still loses connection. Thanks for any explanation and help.
