Epson LQ-850 Manuel D’Utilisation

You can also create superscript and subscript user-defined

characters. Just as Letter Quality characters are defined when the
Letter Quality mode is selected, super/subscript characters are

created when either superscript or subscript is selected.

These super/subscript characters can be used either as superscripts

or as subscripts. The characters are exactly the same; it is only their

placement that differs. The difference between super/subscript
characters and regular characters is that they are smaller. They are a
maximum of 16 dots high and their width in dot columns is shown
in the table below:

Since super/subscript characters are smaller, they don’t require as

much information when you define them. When you define

super/subscript characters, you need only two bytes of data for
each vertical row of dots. Design grids for these characters are

shown in the figure below.
