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
"e"
denotes the bit 1 and a blank box denotes the bit O.
­
According to Appendix F, Code Tables, you can define (0010001O)z as (34)D and
(01010000)2 as (80)D'
­
As you can see, the first 4 bits are defined from column and the second 4 bits are
defined from row. Namely,
­
(0101)2 = (5)D and (0000)z= (O)D'
