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;
87=0 87=0
86=0
•
86=1
•
85=1
85=0
84=0
•
84=1
83=0
83=0
82=0 82=0
•
81=1
81=0
80=0
80=0
(34)0
(80)0
where a box with "e" denotes the bit 1 and a blank box denotes the bit O.
According to Appendix E, Code Tables, you can define (00100010h as (34)D or
<22>H and (OlOlOOOOh as (80)D or <SO>H.
As you can see, the first 4 bits are defined from column and the second 4 bits are
defined from row. Namely,
(0101h = (S)D = <OS>H and (OOOOh= (O)D = <OO>H.
