Sample Label & Decoding

This page shows an example of a DashLink-generated shipping label and explains how to decode it. DashLink returns the label in base64-encoded form.

Example Label (PDF Base64)​

"label_string": "JVBERi0xLjQKJfbk...."

This string represents an entire 4×6 PDF document.

How to decode base64 to PDF​

Example (JavaScript/Node):

const fs = require('fs');

function decodeLabel(base64String, outputPath) {
  const buffer = Buffer.from(base64String, 'base64');
  fs.writeFileSync(outputPath, buffer);
}

decodeLabel(label_string, './label.pdf');

Similar in Python:

import base64

with open("label.pdf", "wb") as f:
    f.write(base64.b64decode(label_string))

Example ZPL label​

DashLink may also return ZPL strings (203 or 300 DPI). These strings can be sent directly to a Zebra printer.

Example pattern (shortened for illustration):

^XA
^CF0,60
^FO50,50^FDStoreName^FS
...
^XZ
