Note

This command will cancel any user-defined characters you have created. You must send this command to the printer before you define characters.

If you use this command at the beginning of a program, then define your special characters and select the user-defined character set, you can print with the user-defined set as your normal character set. You’ll never need to switch back and forth between sets.

Letter Quality characters

If you select Letter Quality printing with the ESCape “xl” com- mand, 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 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 will yield 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, as in draft, 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 charac- ters. 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
