defined by xL, xH, yL, and yH, the printer will process the range
defined by xL, xH, yL, and yH outside the defined range.
In the first group of NV bitmaps, when any one of xL, xH, yL, yH is
out of the definition range, this command is disabled.
In groups of NV bitmaps other than the first group, when 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 bitmaps that haven’t
been defined are disabled (undefined), but any NV bitmaps 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 bitmap. Numbers
rise in order from NV bitmap 01H. Therefore, the first data group [xL
xH yL yH d1...dk] is NV bitmap 01H, and the last data group [xL xH yL
yH d1...dk] is NV bitmap n. The total agrees with the number of NV
bitmaps specified by the command FS p.
The definition data for an NV bitmap consists of [xL xH yL yH
d1...dk]. Therefore, when only one NV bitmap 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 bitmaps, but cannot define bitmap
data whose total capacity [bitmap 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 bitmap is defined, it is not erased by performing ESC
@, reset, and power off.
This command performs only definition of an NV bitmap and does
not perform printing. Printing of the NV bitmap is performed by the FS
pcommand.
