command.
From the beginning of the processing of this command till the
accomplishment of hardware reset, mechanical operations (including initializing
the position of the print head when the cover is open, paper feeding using the
FEED button, etc.) cannot be performed.
During this command processing, the printer is busy and stops receiving
data when writing data to the user's NV memory. Therefore, data transmission,
including real-time commands, is prohibited during the execution of this
command.
NV bitmap is a bitmap defined in non-volatile memory, Define FS p
printing with FS q.
In standard mode, this command is valid only when processed at the
beginning of the line.
This command is valid when 7 bytes <FS yH> of the command are
processed normally.
When the data volume exceeds the left capacity of the range 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,
