angularjs - Node JS - Use Printer (Hardware)

I'm developing an application with Angular JS and Node JS where I need to see all available printers in the user's machine, let the user select one of them and print a receipt.

Is there a way to achieve this?

I did an application like that.. I did it using http://nwjs.io/ and the module in the comment: https://www.npmjs.com/package/printer, here is a working code with this module printing raw in the default printer a file:

var printer = require('printer');
var fs = require('fs');

var info = fs.readFileSync('ticket.txt').toString();

function sendPrint() {
  printer.printDirect({
    data: info,
    type: 'RAW',
    success: function (jobID) {
      console.log("ID: " + jobID);
    },
    error: function (err) {
      console.log('printer module error: '+err);
      throw err;
    }
  });
}

sendPrint();

you can adapt it to use the getPrinters() method to enumerate all installed printers and then allow the user to select the desired one.
