(14)Bit Image Printing (ESC +“K”+ n1 + n2 + n3) 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.
