yL, yH out of the defined range, it stops processing this command and starts writing
into the NV images. At this time, NV bit images that haven’t been defined are disabled
(undefined), but any NV bit images before that are enabled.
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 512K bits (64K bytes). This
command can define several NV bit images, but cannot define a bit image data whose
total capacity [bit image data + header] exceeds 512K bytes (64K bytes).
(Different printer download different space, please refer to printer configuration)
During the processing of this command, the printer does not transmit status and does
not respond to status inquiry as well.
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.

When xL = 64, xH = 0, yL = 96, yH = 0
