[Description] • Copies the setting stored in the active area to the mth storage area.
[Notes] • Frequent write command executions by this command may damage the NV memory.
Therefore, it is recommended to write to the NV memory no more than 10 times a day.
• While processing this command, the printer is BUSY while writing data to the NV user
memory and stops receiving data. Therefore it is prohibited to transmit data, including the
real-time commands, during the execution of this command.
