These examples are deprecated. I have kept them for compatibility purposes. The new and totally documented API is located at https://parzibyte.me/http-esc-pos-desktop-docs/

Remember that, when printing from the browser, you must use https, localhost o 127.0.0.1. It won't work on sites without HTTPS nor localhost with a different port than 80 (which is the default ) nor IP. If you want to print on the local area network, check:How to print on a network printer
If the examples are not working, make sure that:

The plugin is running in the background. Download it from: https://parzibyte.me/http-esc-pos-desktop-docs/es/guia/descargar.html
Your printer is shared and has a friendly name as indicated in: https://parzibyte.me/blog/en/2019/10/13/how-to-share-printer-windows/

Print webpage

Webpage URL

Webpage width

Image width

Image printing algorithm

The webpage shouldn't load external images, scripts nor styles, but have them inline. Don't:

<script type="text/javascript" src="script.js"></script>

Do this:

<script type="text/javascript">
    // Here goes the JS code
</script>

The same applies for CSS styles and images
