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. You can design characters 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 you select either superscript or subscript. 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: Mode Draft Letter Quality Proportional dl dO+dl+dZ 7 12 23 36 23 42 Software and Graphics 4-31
