dymojs

Build Status

Wicked simple pure javascript cross platform Dymo Labewriter printing module for Node.js with no platform dependencies.

This module works on Mac, Linux, and Windows.

  • no gyp build needed
  • no Microsoft Visual Studio needed.
  • no gcc or c++ build needed

install

yarn add dymojs

or if you are stuck in the old school

npm i dymojs

usage

const Dymo = require('dymojs'),
	   dymo = new Dymo();

dymo.print('DYMO LabelWriter 450', labelXml);

render a label preview

dymo.renderLabel(labelXml).then(imageData => {
	// returns imageData as base64 encoded png.
	// use <img src="data:image/png;base64,${imageData}"/>
	// or require("fs").writeFile("out.png", imageData, 'base64', function(err) {...});
});

how do I get the xml for a label?

Open the free DYMO Label software and design a label. When you have designed one save it. The file it saves is an XML document like the one below. Simply pass that XML or (hint hint) a version of that XML that you did some string replacement on to the print function with a printer name and you are printing labels.

working example that prints a test label

This example will print TEST123 on a shipping size label (2 1/8" x 4") to a printer named 'DYMO LabelWriter 450'.

const Dymo = require('dymojs'),
	   dymo = new Dymo();

dymo.print('DYMO LabelWriter 450', labelXml);

var labelXml = `
<?xml version="1.0" encoding="utf-8"?>
