The ZPL printer is designed to allow you to change printer settings dynamically for a fast first label out of the printing. Printer parameters that are persistent will be retained for future format 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 (
) saves and restores printer configurations to initialize (or re-initialize) the printer with pre-configured settings.
