•The d indicates the definition data. In data (d) a 1 bit specifies a dot to be printed and a 0 bit specifies a dot not to be printed.

•This command defines n as the number of a NV bit image. Numbers rise in order from NV bit image 01H. Therefore, the first data group [xL xH yL yH d1...dk] is NV bit image 01H, and the last data group [xL xH yL yH d1...dk] is NV bit image n. The total agrees with the number of NV bit images specified by command FS p.

•A definition data of a NV bit image consists of [xL xH yL yH d1...dk]. Therefore, when only

one NV bit image is defined n=1, the printer processes a data group [xL xH yL yH d1...dk] once. The printer uses ([data: (xL + xH ⋅ 256) ⋅ (yL + yH ⋅ 256) ⋅ 8] + [header :4]) bytes of NV memory.

•The definition area in this printer is a maximum of 2M bits (256K bytes). This command can

define several NV bit images, but cannot define a bit image data whose total capacity [bit image data + header] exceeds 2M bytes (256K bytes).

• The printer is busy immediately before writing into NV memory, regardless of the setting of

	DIP switch 2-1.
	• The printer does not transmit ASB status and perform status detection during processing of
	this command even when ASB is specified.
	• When this command is received during macro definition, the printer ends macro definition,
	and begins performing this command.
	• Once a NV bit image is defined, it is not erased by performing ESC @, reset, and power off.
	• This command performs only definition of a NV bit image and does not perform printing.
	Printing of the NV bit image is performed by the FS p command.
[Notes]	• Frequent write command execution may cause damage the NV memory.
	Therefore, it is recommended to write the NV memory 10 times or less a day.
	• The printer performs a hardware reset after the procedure to place the image into the NV
	memory. Therefore, user-defined characters, downloaded bit images, and macros should be
	defined only after completing this command. The printer clears the receive and print buffers
	and resets the mode to the mode that was in effect at power on. At this time, DIP switch
	settings are checked again.
