Printing from an Android Web Session directly to a GX420t via Bluetooth

Hi

I have a customer who wants to print Tickets directly from a web session with is running on an Android Tablet.

Apparently the customer tested the solution on a loan printer which was connected via USB and it all worked fine.

 

The decided however to purchase 3 x GX420t printers and they are unable to get the printing solution to work via a BT connection.

They are looking for assistance to solve this.

 

Is it at all possible to do this without any App development on the Android device?
