Epson GT-9500 [43/54] Set line counter

7/8/96-B 41

Set line counter

(1) Code: ESC d

ASCII: ESC d i

decimal: 27,100 i

hexadecimal: 1B,64 i

(2) Function: This command sets the number of the Line Counter in the Block data structure,

and the parameter ‘i’ indicates the number.

The Block data transfer mode is available only when setting this code.

0 < i ≤ 255

(3) Handshaking

1) ESC d code

2) ACK( 06H )

3) i (1 byte)

Note1: This setting is not remained once executing a scanning start

[ESC G]. It means that the data transfer mode is always the Line

data mode without setting this code. Therefore this code should

be set whenever using the Block data structure.

Note2: In the case of the color line scanning mode, the number of the

line for image data should be counted separately for each color

R, G and B.

Note3: The number of the Line counter in the last data block may not be

‘i’ because it is calculated by the following expression.

Therefore the Line Counter should be refereed in order to receive

the image data.

The last line counter = mod[ SSRL/i]

Where SSRL is a Sub Scan Read Length (Ref. [ESC A]) ,

and the ‘mod[]’ is a function to get a remainder divided by ‘i’.
