A printer that supports ZPL allows you to change printer settings dynamically to enable fast, first-label-out printing.
When established one time, persistent printer parameters are retained for use for subsequent printing. They remain in effect until:
they are changed by subsequent commands,
printer settings or one or more parameters are reset to their factory defaults, or
printer power is cycled.
The
^JU
ZPL Configuration Update command saves and restores printer configurations to initialize or re-initialize the printer with pre-configured settings.
To retain all current persistent settings after a power cycle or printer reset, send the
^JUS
command to the printer.
ZPL stores all parameters when this command is issued. The legacy EPL programming language (supported by this printer) changes and saves individual commands immediately.
To restore the last saved values to the printer, use the
^JUR
command.
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 modified EPL setting will persist even after a power cycle or reset issued by either printer language.
The Printer Configuration report is useful list of operating parameters, sensor settings, and printer status. You can print one using the steps in Testing Printing with the Configuration Report or through the Zebra Setup Utilities or ZebraDesigner Windows driver.
