Hello, Has anybody used the Serial Manager API for printing using a USB cable from an Alphasmart Dana? We need to use the New Serial Manager API version 2 for USB communication. My Dana does not have the Serial Manager Version 2 installed, but it has version 1 installed. Does anyone know how to install it? If anybody has any clue, pls reply.
