4.3. Relationship between data and dot wires

Fig. 68 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.

If a bit is “1,"the print head fires. If a bit is “0,”the print head does not fire. For example, assume that data are given as follows;

where a box with “•”denotes the bit “1” and a blankb o x denotes the bit “0.” According to Appendix 3, Code Table, you can define (00100010)2 as <22>H and

(01010000)2 as

<50>H .

A s you can see

the first 4 bits are defined from column and the second 4 bits

are defined from row. Namely,

( 0 1 0 1 )2 = <5>H ,

and (0600)2 = < O >H.
