/*
 * 
 * Connectivity Demo
 * The purpose of this demo program is to demonstrate how to connect with
 * a Bluetooth or Wireless printer. The program will do the following:
 * 1. Depending on which radio button is selected, will establish a connection to a Zebra printer
 * 1a. If bluetooth, will connect via the MAC address specified by the user
 * 1b. If Wi-Fi, will attempt to connect via the BlackBerry(R) Mobile Data Service. If connection fails will retry with direct Wi-Fi (JDE 4.6.0 or higher)
 * 2. Will interrogate the printer for the printer control language
 * 3. Will send a test label (based on the printer control language) to the printer
 * 4. Will disconnect from the printer
 *
