[Reference] FS p
[Example] 当 xL=64, xH=0, yL=96, yH=0
In standard mode, this command is effective only when processed at
the beginning of the line.
This command is effective when 7 bytes<FS yH> of the command
are processed normally.
When the amount of data exceeds the capacity left in the range
defined by xL, xH, yL, yH, the printer processes xL, xH, yL, yH out of
the defined range.
In the first group of NV bit images, when any of the parameters xL,
xH, yL, yH is out of the definition range, this command is disabled. In
groups of NV bit images other than the first one, when the printer
encounters xL, xH, 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 the command FS p.
The definition data for an 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 192K bytes. This
command can define several NV bit images, but cannot define bit
image data whose total capacity [bit image data+header] exceeds
192K bytes.
The printer does not transmit ASB status or perform status detection
during processing of this command even when ASB is specified.
Once an NV bit image is defined, it is not erased by performing ESC
@, reset and power off.
This command performs only definition of an NV bit image and does
not perform printing. Printing of the NV bit image is performed by the
FS p command.
