[Notes] • Frequent write command executions by an NV memory write command may damage
the NV memory. Therefore, it is recommended to write to the NV memory less than
10 times a day.
• If the power is turned off or the printer is reset via an interface while this command is
being executed, the printer may go into an abnormal condition. Be careful not to
turn the power off or let the printer be reset via an interface while this command is
being executed.
• While processing this command, the printer is BUSY while writing the data to the NV
memory and stops receiving data. Therefore, be sure not to transmit data, including
the real-time commands, while the printer is BUSY.
• When <Function 1, 6, or 12> is transmitted, the data following must not be
transmitted until the status is received.
