Select Justification
Comments:
The following values can be used for n:
0: Selects left justification.
1: Selects centering.
2: Selects right justification.
3: Selects full justification.
The default setting is n = 0. Full justification
(n
= 3) is performed
when the buffer becomes full; HT, BS, and spacing commands should
not be used with justification. For n = 3 there must be no carriage
returns within a paragraph.

Set Intercharacter Space
Comments:
Sets the amount of space added to the right of each character, in
addition to the space already allowed in the design of the character.
The number of dots is determined by n, which should be from 0-127.
Each unit of space is 1/120th of an inch in draft and l/l80th of an
inch in Letter Quality and proportional. Double-wide doubles the unit
of space.
