Table 4. 6-bit mapping
6 BITS IN 1 BYTE
PRINT HEAD WIRE DATA BIT
1 2 & 3 0
3 4 & 5 1
6 7 & 8 2
8 9 & 10 3
11 12 & 13 4
13 14 & 15 5
Since bits 6 & 7 are ignored, wires 16-24 are not used. The state (0 or 1) of bits 6 and 7 must be conditioned so as
to make the entire byte fall within the range 20H through 7EH.
