Print on android cordova serial port

Hello, I want my android app (Cordova) to use my serial port printer. there is java code here and also Cordova plugin attached. You can see the java priting functions in [login to view URL] and you will also see the same serial interfaces in both the java and cordova plugins, we want the printing from my cordova application (kept private for now) to use the serial printer. it should be simple if you have knowledge of android and cordova. thanks.
