JS ERROR TypeError: Object is not a constructor

[d3mac123]

Hi, I am trying to using the plugin with plain Javascript. However, writing this:

var Printer = require("nativescript-printer")
var printer = new Printer();

I am getting the following error:

***** Fatal JavaScript exception - application has been terminated. *****

JavaScript error:
file:///app/flight-page.js:27:26: JS ERROR TypeError: Object is not a constructor (evaluating 'new Printer()')

Any ideas on how to fix it?

With JavaScript it should be:

var printerPlugin = require("nativescript-printer")
var printer = new printerPlugin.Printer();
