I need to print on a Bluetooth printer. I already have a program for the Windows mobile platform, that sends commands and data via Bluetooth to a Zebra RW 420 printer, using the Zebra Printer Protocol. It's just a stream sent on Bluetooth.

Your best bet will be to use the ZebraLink SDK for Android devices. You can download it from Zebra here. The SDK comes with a load of sample code and documentation which covers how to use it, so you should be able to jump right in!
