When configuring App printing from Android devices, it can sometimes be a little hard to  determine the source of a timeout or similar.

Most of the time there is a network port not being open in firewalls between the mobile device on the WiFi network and the EveryonePrint servers with mobile gateways.

Use the following simple method to verify if a port is open and accessible from the Android device:

1. From the Google Play store  install a network tool utility like "IP Tools" app
2. From the App menu, choose Port ScannerEnter the destination DNS/hostname/IP address of the server hosting the EveryonePrint Mobile Gateway and the port to test, ie port 9444 for the Mobile Gateway TCP port
3. Verify that the port is available
