[Description] Transmits data from NV user memory.

	• m is always set to 0.
	• a1, a2, a3, and a4 specify the data stored starting address to
	(a1+(a2⋅ 256)⋅ (a3⋅ 65536)+(a4⋅ 16777216)).
	• nL, nH select the number of stored data bytes (nL+(nH⋅ 256)).
[Details]	• NV user memory means the memory area which is used for storing character font data in
	non-volatile memory.
	• If the values of the argument (m), the stored starting address (a1, a2, a3, a4) and the number
	of the stored data (nL, nH) are out of the specified range, or if the stored staring address (a1,
	a2, a3, a4) + the number of the stored data (nL, nH) ≥ 1024, this command is ignored and
	data following are processed as normal data.
	• After the data is ready to be transmitted, the printer executes the following process.
	① Executes READY to BUSY. If it is already BUSY, the printer executes nothing.
	② Transmits [Header + Data + NUL].
	③ Executes BUSY to READY. If it is already BUSY from any other cause, the printer
	executes nothing.
	• The contents of [Header + Data + NUL] are as follows:

Header: Hexadecimal = 5FH / Decimal = 95 (1 byte)

Data:	Data stored in NV user memory ((nL+(nH⋅ 256)) bytes)
NUL:	Hexadecimal = 00H / Decimal = 0 (1 byte)

•When DTR/DSR control is selected, the printer transmits data consecutively after confirming whether the host computer is ready to receive data. When the host is not ready to receive data, the printer waits until the host is ready.

•When XON/XOFF control is selected, the printer transmits all data consecutively without confirming whether the host computer is ready to receive data. The data transmission must be consecutive, except for the XOFF code.

•With the parallel interface mode, the data buffer capacity (which is the memory area to store all transmitted data except ASB status) is 99 bytes. Data which exceeds 99 bytes are ignored.

•Data which is stored in the NV user memory can be written by FS g 1.
