You are welcome! It looks like the ping test was a success, It's possible that the wireless router is blocking or not able to forward multicast packet (Bonjour). Multicast packet (Bonjour) allows Apple devices to locate the printer on a WiFi network. Please contact your internet service provider or router manufacturer and check if the router is able to forward multicast packet. If the router is able to forward multicast packets then use the steps available here to troubleshoot the connection issue.
