prohibited 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 the 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 image, when any of the parameters xL, xH, yL,
yH, is out of the definition range, the command is disabled.
·In groups of NV bit image other than the first one, when the printer
processes xL, xH yL, yH out of the defined range, it stops processing this
command and stars writing into the NV images. At this time, NV bit image
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 image. Number 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 vL vH 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 image, 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.
