THERMAL RECEIPT PRINTER
32
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 processes
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 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: (

[header :4])bytes of NV memory.
The definition area in this printer is a maximum of 0.5M 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 0.5M bits (64K bytes).
The printer is busy immediately before writing into NV memory.
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.
[Details]
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.
