4.3 Relationship between data and dot wires
Fig. 63 shows the relationship between the Bit Image data and the dot wires in the
print head. You can control arbitrary 8 dot wires in the print head.

Fin. 63 Relationship between Data and Dot Wires
If a bit is “1“, the print head fires. If a bit is “0”, the print head does not fire. For ex-
ample, assume that data are given as follows;
B7=0
B6=0
B5=1
B4=0
B3=0
B2=0
Bl-1
BO=O
<22>,,
67=0
B6=1
B5=0
B4=1
B3=0
B2=0
Bl-0
BO=O
<50>,,
where a box with
“0”
denotes the bit “1” and a blank box denotes the bit “0”. Ac-
cording to Appendix 4, Code Table, you can define (00100010)2 as
<
22
>
H and
(01010000)2as
<50>H.
As you can see the first 4 bits are defined from column and the second 4 bits
(0101)2-
<5>H,and
(0000)2-
<O>H.
