User-defined Characters
Letter Quality Characters
If you select Letter Quality printing with the ESC xl command, you
can design user-defined characters using up to 29 columns of the
Letter Quality/Proportional grid. The dot columns are spaced closer
together horizontally than draft 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 Letter Quality and proportional modes, as in
draft mode, you cannot place dots in adjacent columns. There must
be an empty dot position both 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; only their placement is
different. The difference between these characters and regular
characters is that superscript and subscript characters are smaller.
They are a maximum of 16 dots high. Their maximum width in dot
columns is shown in the table below:
