What is ZPL?

ZPL (Zebra Programming Language) is a programming language developed by Zebra Technologies to control their thermal printers. ZPL uses specific commands to define the format, position, and content of labels, including text, barcodes, and graphics.

ZPL files contain instructions that the printer interprets to generate physical labels. These instructions are composed of commands that begin with the character "^" followed by letters indicating the action to perform.
