The required total number of bitmap image data is
((nL + nH x 256) x no. of data per line) bytes.
The format of bitmap data for a printer with n heating
elements in the head is as follows:
MSB LSB
d1 d2 d3 ...... d (n/8)
d (n/8)+1 d (n/8)+2 d (n/8)+3 ...... d (2n/8)
d (2n/8)+1 d (2n/8)+2 d (2n/8)+3 ...... d (3n/8)
:
:
.......
d (nL+nHx256)x(n/8)
