which can be checked through printing self-test page. The download FLASH bitmap
should be no larger than Flash download capacity, otherwise download will fail.
• n specifies the number of the defined NV bitmap
• yL
、
yH specifies ( yL + yH × 256) × 8 dots in the horizontal direction for the NV
bitmap you are defining.
• zL
、
zH specifies ( zL + zH × 256) × 8 dots in the vertical direction for the NV bitmap
you are defining.
• This command is disabled in upside-down printing mode.
•
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.
·This command cancels all NV bitmaps that have already been defined by this command.
The printer can not redefine only one of several data definitions previously defined. In
this case, all data needs to be sent again.
· Before the ending of the processing of this command 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, also sending command including real-time
command is forbidden.
•
NV bitmap means a bitmap which is defined in a non-volatile memory by
FS r
and
printed by
FS p
.
• · In standard mode, this command is effective only when processed at the beginning of
the line.
This 9 bytes <from FS~zH> is command data but not data of image.
In the first group of NV bitmaps, when any of the parameters yL,yH,zL,zH is out of the
definition range, this command is disabled.
In groups of NV bitmaps other than the first one, when the printer processes
yL,yH,zL,zH out of the defined range, it stops processing this command. 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[yL yH zL zH d1...dk] is NV bitmap 01H,
and the last data group[yLyH zL zHd1...dk] is NV bitmap n. The total agrees with the
number of NV bitmaps specified by command FS p.
A definition data of a NV bitmap consists of [yL yH zL zH d1...dk]. Therefore, when only
one NV bitmap is defined n=1, the printer processes a data group [yL yH zL zH d1...dk]
once. The printer uses ([data:
(
yL
+
yH ×
256
)
×
(
zL
+
zH ×
256
)
×
8] + [header:4])
bytes of NV memory.
• When processing this command, the printer does not process other commands.
