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, 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 Table 6-4.

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 Figure 6-g on the following page.

Mixing print styles

Each of the three user-defined character modes (draft, Letter Quality and proportional) can be used in combination with most of the LQ-2500’s various print styles, such as emphasized and double-width, but not with italic or super/subscript.

Mixing the three types of user-defined characters is not permitted. If, for example, you select draft and define some characters, then select proportional and define some more, the first character definitions will be destroyed. Only one type of character definition may be stored in RAM at any time.
