node-zpl

node-zpl is a ZPL (Zebra Programming Language) generator for Node.js written in Typescript.

This library provides a thin (but typed!) wrapper around the ZPL commands as described by Zebra.

[!NOTE] This library is under active development and does not yet support every single ZPL command. Please check the table below to see the currently supported commands. Contributions are welcome!

Installation

Install node-zpl using the package manager of your choice. Using npm:

npm install node-zpl

Usage

Here's a basic example of how to use node-zpl to generate a label with a EAN-13 bar code:

import { Label, Orientation } from "node-zpl";

const label = new Label(57, 19, 12)
  .drawEAN13({
    position: {
      x: 10,
      y: 20,
    },
    orientation: Orientation.Normal,
  })
  .close();
const zpl = label.dumpZPL();

[!TIP] To preview your generated ZPL you can use Labelary!

You can also convert an image to something usable in ZPL by using the provided ImageConverter:

import { ImageConverter } from "node-zpl";
import { readFileSync } from "fs";

const converter = new ImageConverter();
const buffer = readFileSync("./assets/test-image.png");

const zpl = await converter.toZPL(buffer);
