Pica

 

 

 

 

 

 

 

Figure 3-2. The three pitches of the LX-80

The dot pattern of each character is carefully designed so that in

pica mode no dot overlaps another. The reason is that in normal
high-speed printing of pica the pins cannot fire and retract and fire
again quickly enough to print one dot overlapping another.
