Registering the bit map data/ESC~b
[ASCII]
ESC ~ b FFh n1 n2 d1 d2 d3 … dn 0 0
[Decimal] 27 126 98 255 n1 n2 d1 d2 d3 … dn 0 0
[Hexadecimal] 1B 7E 62 FF n1 n2 d1 d2 d3 … dn 0 0
[Description]
● Stores Windows bitmap data into the flash memory. The structure of bitmap data is the same as that of BMP file data.
Refer to Windows-related references for more details about BMP files.
● The structure of parameters is as follows.
{n1, n2, d1, d2, d3 … dn} ……… (1)
‘d1, d2 … dn’ is the same as the data structure of BMP files.
n1, n2 specify the BMP file size.
n1 specifies the remainder of BMP file size divided by 256.
n2 specifies the quotient of BMP file size divided by 256.
Sends the BMP file data after sending n1, n2.
Several BMP file data can be written at a time into the flash memory by repeating the parameter sequence (1). BMP file
data are assigned with a number accordingly in sequence from 0, based on which printing of BMP data is executed.
This sequence is completed by specifying 0 in n1 and n2 (no BMP file data).
● A registration area up to 64KB (64 × 1024 = 65536 bytes) is available.
● BMP file data registered in the flash memory before this command is sent will be all deleted.
● Data writing to the flash memory is available only a limited number of times. Avoid registering BMP files on a regular
basis.
● Do not use this command together with other print commands because it writes data into the flash memory.
【 Restriction in BMP file 】
● BMP files support only two-color materials.
● It does not support color pallets.
