· From the beginning of the processing of this command till the finish of hardware
reset,mechanical operations (including initializing the position of the printer head
when the cover is open, paper feeding by using the FEED button, etc.) cannot be
performed.
· During processing this command, the printer is in BUSY when writing the data to
the NV user memory and stops receiving data. Therefore it is prohibitted to transmit
the data including the real-time commands during the execution of this command.
· NV bit image means a bit image which is defined in a non-volatile memory by FS q
and printed by FS p.
· In standard mode, this command is effective only when processed at the beginning
of the line.
· In page mode, this command is not effective.
· This command is effective when 7 bytes <FS<yH> is processed as a normal value.
· 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 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: (xL + xH

+ [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.
