ZPL Basics

Overview

ZPL is designed to provide simple, flexible commands that can be generated with

common, basic PC programs. ZPL command files can be sent quickly and processed by

most host systems using typical operating system commands (i.e. DOS COPY command)

or develop applications (using other host to device communication methods). Because of

this, your application’s ZPL code and your kiosk printers are easily maintained. To make it

even easier for you, Zebra has several utilities and applications which were used in earlier

chapters to create a prototype receipt and prepare the printer for the ZPL development

process.

The ZPL Command

ZPL commands consist of a prefix character, a two-character mnemonic code and, where

applicable, a parameter string. The entire language is programmable in printable ASCII

characters, which allows easy passage of formats and data through computer networks

and protocol converters. ZPL commands do not have to use escape sequences or control

codes. A few printer instructions do have ASCII control code equivalents, which are noted

as they apply within the ZPL Programmers guides and in some instances, here in this

guide.

You can create and use ZPL scripts (receipt and label formats or forms) using any text

editor capable of generating an ASCII text file. You can integrate your Zebra printer into

your operations by using database programs and other languages to generate ZPL

programming to send to the kiosk printer. The ZPL program is then sent to the Zebra

printer through an appropriate interface (combination of proper cabling, printer

configuration, and software settings). The examples in this guide use printable ASCII

characters in all instructions, unless otherwise noted.

There are two types of ZPL instructions: Format commands, which get processed in order

received and Control commands, which get processed immediately. There are several

commands that also control the printer function, but are not an immediate commands so

they are grouped with the Format commands.
