(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.

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. With this printer, on completion of read-in of 4-dot-line data or on completion of n1/n2/n3 assigning data, lacking data are printed 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.
