HP 7520 WiFi scanning not working Mac OS High Sierra
If when installing an HP 7520 WiFi printer with HP Easy Start you get a warning that the scanner does not support “Bonjour” then you may end up with a working printer but no scanner!
In most cases this happens because you have a dual band router advertising 2.4GHz and 5GHz on the same SSIDs. In short the HP 7420 only works with the 2.4GHz network.
One solution is to disable the 5GHz network or rename it and only connect the Mac and printer to the 2.4GHz SSID network.
