[Caution]	• Because frequent writing in the non-volatile memory can
	destroy the memory, the writing command (FS g3) should be
	used less than 10 times a day.
	• It may happen that the printer becomes BUSY during the
	process of writing data into the non-volatile memory while
	this command is executed. When the printer becomes BUSY,
	it will stop receiving data. Therefore, sending data from the
	host (Including real time commands) is prohibited.
