How to Print Labels from Node-RED Using ZPL (Step-by-Step Guide)

In this video, I’ll walk you through how to print labels from Node-RED using ZPL (Zebra Programming Language), step by step. We’ll start from configuring a network label printer, creating and testing ZPL code using Labelary, and then building a simple Node-RED flow to send print commands directly to the printer over TCP/IP. You’ll also learn how to: • Set up printer communication over Ethernet • Understand basic ZPL structure and commands • Preview label designs before printing • Send ZPL code from Node-RED using a function node • Create dynamic labels using a simple input form • Perform test prints and troubleshoot common issues This tutorial is perfect for anyone who wants to integrate label printing into their automation system using Node-RED.
