What is ZPL?

ZPL (Zebra Programming Language) is a printer control language used by Zebra thermal printers. It's the standard format for creating shipping labels, barcode labels, and other thermal printer output. Our free ZPL viewer lets you preview your ZPL code before sending it to your printer.

How to Use the ZPL Viewer

Simply paste your ZPL code into the text area above and click "Preview ZPL Label". The viewer will render your ZPL code at 203 DPI, which is the standard resolution for Zebra thermal printers. This helps you verify your label design before printing.

This ZPL preview tool is compatible with all Zebra thermal printers that support ZPL format, including popular models used for shipping labels like the ZP450, GK420d, and ZD420. Preview your 4x6 shipping labels and other thermal label formats.
