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 its 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 you as a reference. It lists operating parameters, sensor settings and printer status, and can be printed as described in Test Printing with the Configuration Report. The Zebra Setup Utility and the ZebraDesigner Windows driver also print this report and other printer reports to help you manage your printer.
