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=067=0

B6=0B6=1

B5=1B5=0

B4=0B4=1

B3=0B3=0

B2=0B2=0

Bl-1Bl-0

BO=OBO=O

<22>,,<50>,,

where a box with “0”denotes the bit “1” and a blank box denotes the bit “0”. According 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.
