* 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
