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:

1npm 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:

1import { Label, Orientation } from "node-zpl";
2
3const label = new Label(57, 19, 12)
4  .drawEAN13({
5    position: {
6      x: 10,
7      y: 20,
8    },
9    orientation: Orientation.Normal,
10  })
11  .close();
12const 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:

1import { ImageConverter } from "node-zpl";
2import { readFileSync } from "fs";
3
4const converter = new ImageConverter();
5const buffer = readFileSync("./assets/test-image.png");
6
7const zpl = await converter.toZPL(buffer);
