printing simultaneously on 2 or more printers

Hi Arnold,

I've never tried it, but you should be able to make a connection to two different printers from one Android device.  Each printer can only be connected to one Android device.  I do know you can make multiple connections to multiple printers over WiFi.  You can open a standard TCP socket to port 9100 on each printer IP address. 

You can also use the Link-OS Multiplatform SDK to help with Bluetooth and TCP communications.
