How It Works​

Sales & Dungeons

Templates: Templates are created in HTML (and CSS) in combination with the Nunjucks templating language. You can imagine the templates as little websites. That makes it possible to use all the nice and convenient layout options that HTML and CSS has to offer and even include any common framework you might need (e.g. Fontawesome for Icons).

Rendered HTML: After creating a template you can create entries with the data you want and print them. Nunjucks will create the rendered HTML from the data you want to print.

Rendered Image: Then this HTML get's converted to a image. Currently this conversion is done by Chrome via the Chrome Debug Protocol. Although Chrome seems like a huge overkill for just HTML-To-Image conversion it's the standard solution at the moment because it supports most of the modern HTML and CSS features.

ESC / POS Commands: The last step before our awesome template hits the Printer is the conversion from the rendered image to the "draw image" command of the printer.

Printer: The generated command will then be sent to the printer and printed. Now your template is ready to be used!
