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 future 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 resetting
the printer to factory defaults. 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 the
printer.
ZPL stores all parameters at once with a single command mentioned above. The legacy EPL
programming language (supported by this printer) changes and saves individual commands
immediately. Most printer 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.
A printer Configuration Report is available to assist the developer. The Configuration Report lists
operating parameters, sensor settings, and printer status. It can be accessed by using the
procedure in Test Printing with the Configuration Report on page 41. The Zebra Setup Utility and
the ZebraDesigner ™ Windows driver also print this report and other printer reports to help you
manage your printer.
ZPL Printer Configuration Format
Managing more than one printer can be done by 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 Configuration Setting to Command Cross-reference
on page 146 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.
