Managing the ZPL Printer Configuration

Managing the ZPL Printer Configuration

The ZPL printer is designed to allow you to change printer settings dynamically for fast first label out printing. Printer parameters that are persistent, will be retained for following formats to use. Those settings will remain in effect until they are changed by subsequent commands, the printer is reset, power is cycled, or when you restore a parameter that has a factory default by using the Feed Button Mode four (4) flash routine. The ZPL Configuration Update command (^JU) saves and restores printer configurations to initialize (or re-initialize) the printer with pre-configured settings.

•To keep settings after a power cycle or printer reset, a ^JUS can be sent to the printer to save all current persistent settings.

•The values are recalled with a ^JUR command to restore the last saved values to you printer.

ZPL stores all parameters at once with a single command discussed above. The legacy EPL programming language (supported by this printer) changes and saves individual commands immediately. Most configuration and settings are shared between ZPL and EPL. For example, changing the speed setting with EPL will also change the speed set for ZPL operations. The changed EPL setting will persist even after a power cycle or reset issued by either printer language.

To assist the developer, the printer has a listing of the operating parameters, a Printer Configuration Label. It can be accessed by using the printer’s Feed button and the Printing a Test (Printer Configuration) Label on page 19. The Zebra Setup Utility and the ZebraDesigner™ Windows driver also print this label and other printer status labels to help you manage your printer.

ZPL Printer Configuration Format

Managing more than one printer can be done creating a printer configuration programming file to send to one or more printers or ZebraNet™ Bridge can be used to clone a printer’s setup. Figure 1 below shows the basic structure of a ZPL programming configuration file.

See the ZPL programmer’s guide and the ZPL Configuration Status to Command Cross- reference on page 89 to create a programming file. The Zebra Setup Utility (ZSU) can be used to send programming files to the printer. Windows Notepad (text editor) can be used to create programing files.

The GC420t is also equipped with diverse connectivity options, including USB, serial, and parallel interfaces. This flexibility allows for easy integration into various environments and simplifies the connection to computers and other devices. Moreover, the printer's compact design ensures it can fit comfortably in small spaces, making it ideal for environments with limited room.

When it comes to media handling, the GC420t supports a wide range of label sizes and types. Whether you need to print shipping labels, barcode labels, or asset tags, this printer can accommodate your requirements. The adjustable media guides allow for quick and easy adjustments to suit different media types.

In conclusion, Zebra Technologies GC420t stands out as a reliable, efficient, and user-friendly thermal transfer printer. Its robust features, including high print speed, durable output, versatile connectivity options, and adaptability to various media types, make it an essential tool for businesses looking to enhance their labeling and printing processes. Whether in retail, healthcare, or logistics, the GC420t delivers performance and reliability that organizations require.
