horizontally than draft style dot columns-the horizontal dot spacing is
1/360th of an inch as opposed to 1/120th of an inch for draft characters.
Proportional mode characters
Selecting the proportional character mode yields user-defined characters
of the highest resolution. Characters can be designed using all 37
columns of the Letter Quality/Proportional grid.
Remember that in both Letter Quality and proportional modes, as in
draft mode, you cannot place dots in adjacent columns. There must be
an empty dot position to the left and right of each dot that prints.
Superscripts and subscripts
You can also create superscript and subscript user-defined characters. Just
as Letter Quality characters are defined when the Letter Quality mode is
selected, superscript and subscript characters are created when either
superscript or subscript is selected.
These characters can be used as either superscripts or subscripts. The
characters are exactly the same; it is only their placement that differs.
The difference between these characters and regular characters is that
superscript and subscript characters are smaller. They are a maximum of
16
dots high and their width in dot columns is shown in the following
table.
