Answer 1

This is the most important part of your stacktrace:

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.duplou.cordova.plugin.customprinter.CustomPrinter"

Your Cordova configuration references the CustomPrinter plugin. When Javascript triggers loading it, the Java class cannot be found and thus your application crashes.

You need to ensure that the Java class is present in your application package.
