HTTP API description

This guide assumes the plugin is already running on port 8000. You may change the port, but if you do, change the playground and your code accordingly

The API communicates through JSON. It will accept and answer with JSON

Local API, no internet required

This HTTP to ESC POS API works offline, it executes a HTTP server in your own computer, does not require internet access.

Warning

If you call this API from the browser, make sure you call it from localhost or a site with https, otherwise it won't work.

To print on LAN, check Lan printing

Programming languages

The examples provided are written with JavaScript client-side, but you can call the plugin from any programming language, it's just consuming an API

Changing plugin port

You can specify the puerto command line option. Normally, you run the plugin with:

plugin.exe

Now run it this way:

plugin.exe --puerto NEW_PORT

For example, to run it on 2811 port:

plugin.exe --puerto 2811

On Windows, you can create a shortcut, then go to properties and in Shortcut tab in Target which says something like:

C:\Users\your_user\Location_to_plugin\plugin_v3.5.0.exe

Change to:

C:\Users\your_user\Location_to_plugin\plugin_v3.5.0.exe --puerto NEW_PORT

For example, to change it to port 2106:

C:\Users\your_user\Location_to_plugin\plugin_v3.5.0.exe --puerto 2106

And now, instead of running the plugin directly, run it from the shortcut
