Besides being able to specify the actual width of the
character, this printer allows you to specify the position in the
standard grid where the character will print. You must specify
the dot column in which the printed character starts and the dot
column in which the character ends. Why, you may ask, would
you want to define a character this way instead of merely defin-
ing the overall width of the character? Because this printer’s
draft proportional character definitions can also be used to print
normal width characters, which are twelve dot columns wide.
And by centering even the narrow characters in the complete
grid they will look good even you aren’t printing them propor-
tionally.
The three bytes are used to specify the width of the character
and the space to be allowed on either side of it. The left space (in
dot columns) is specified by m0 and the right space is specified
by m2. The second byte (ml) specifies the number of columns of
dots that will be printed by the character. By varying the width
