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:
