Prntr (Printer)

Github Build Status Software License Standard - JavaScript Style Guide npm bundlephobia

A tiny javascript library to help printing from the web.

Print.js but modern and maintained.

This is a fork of Print.js but transformed into a Typescript package.

Only 3.7kB gzipped!

🙏 Thank you Rodrigo for all your hard work!


You can download the latest version of Prntr from NPM

To install via npm:

npm i prntr --save

To install via yarn:

yarn add prntr


Import the library into your project:

import prntr from 'prntr'

Or use the library directly in a script tag using the umd build and a CDN or such like this:

<script src=""></script>

Browser Support

  • Chrome: Latest 2 versions should work at least
  • Chrome mobile: does not work. It calls onIncompatibleBrowser callback.
  • Chrome tablet: does not work. It calls onIncompatibleBrowser callback.
  • Firefox: Latest 2 versions should work at least. Firefox requires you to set 'open PDF in browser' setting to true in your browser settings to be able to print PDFs and such.
  • Safari: Latest 2 versions should partially work. Safari 14/15 has issues with printing more than once. See this issue on StackOverflow.
  • Safari Mobile: Not working on iphone. It calls onIncompatibleBrowser callback.
  • Safari Tablet: Not working on ipad . It calls onIncompatibleBrowser callback.
  • Edge: Latest 2 versions should work at least. Old EdgeHTML engine should also work. Maybe you need to transpile package though.
  • IE11: NOPE! IE11 is really old and even Microsoft itself stopped supporting it.

Feel free to send pull requests to fix any browser issues!


Extensive examples can be found in the /example html document.
