(13)Bit Image Printing (ESC +“K”) Command

With ESC (1BH) + K (4BH) + n1 + n2 + n3 code being input, conversion from Text mode into Bit Image mode takes place. The n1/n2/n3 assigns amount of transmission of bit image data which follows these. Where, n1 represents the no. of bytes in lateral direction and n2 (lowermost)/n3 (uppermost) represent the no. of dot lines in vertical direction.

[Relations between data and print-out]

n1

1 byte

D8 D7 D6 D5 D4 D3 D2 D1

n3 ⋅ 256 + n2 D1~D8 indicate dot location in each position. No. of dot lines To place a dot in a particular position,

put 1 in binary and 0 for a space.

[Parameter assignable range]

Model	n1	n2	n3
24 columns	1~18	0~255	0~1
40 columns	1~23	0~255	0~1

In case that assignment has been made out of the assignable range or n2 = n3 = 0 has been assigned, Bit Image mode is cancelled and Text mode starts.

On completion of receiving 4-dot-line data or on completion of receiving n1/n2/ n3 assigned data, this printer starts printing with insufficient data treated as spaces.

Note 1: With n1 = 23 having been assigned in 40-column model, 4 dots from the lowermost column (LSC-DOT) are made invalid. This is because the printing position in one line equals 180 dots.

Note 2: On termination of bit image printing, Text mode is reinstated.
