0 8-dot single-density 8 68 102 nL + nH × 256
1 8-dot double-density 8 68 203 nL + nH × 256
32 24-dot single-density 24 203 102 (nL + nH × 256) × 3
33 24-dot double-density 24 203 203 (nL + nH × 256) × 3
 The
nL
and
nH
indicate the number of dots of the bit image in the horizontal direction.
The number of dots is calculated by
nL
+
nH
× 256.
 If the bit-image data input exceeds the number of dots to be printed on a line, the
excess data is ignored.

d
