· This 7 bytes <from FS~yH> is command data but not data of image.
· 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 bitmaps, when any of the parameters xL, xH, yL, yH is out of the
definition range, this command is disabled.
· In groups of NV bitmaps other than the first one, when the printer processes xL, xH, yL,
yH 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 [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 command FS p.
· A definition data of a 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 download area in Flash of this printer is a maximum of 64K bits (8K bytes). This
command can define several NV bitmaps, but cannot define a bitmap data whose total
capacity [bitmap data + header] exceeds 64K bits (The download area is different
according to different configuration).
·
• When processing this command, the printer does not process other commands.
· When this command is received during macro definition, the printer ends macro
definition, and begins performing this command.
· Once a NV bitmap is defined, it is not erased by performing
ESC @
, reset, and power
off.
· This command performs only definition of a NV bitmap and does not perform printing.
Printing of the NV bitmap is performed by the
FS p
command.
