In double-strike mode, the T-750 prints each line twice, with the second slightly below the first. This makes the characters bolder. While NLQ is in use, however, double-strike is ignored because NLQ characters are already formed by two passes of the print head.
This is normal NLQ printing
This is emphasized NLQ printing
Superscripts and subscripts are valuable for such purposes as printing footnote numbers or parts of mathematical formulas, and the underline mode provides an automatic way of underlining fully any piece of text. It underlines spaces, subscripts, and superscripts without a break.
The example below shows underlining with text and combined with superscripts and subscripts in a mathematical formula.

The T-750 incorporates a new character set: Epson Character Graphics. This set allows you to take advantage of the power of the Epson mode commands and still print out the character graphics used by IBM and compatible computers and by much application software. For example, if your word processor can include the characters to draw boxes and shade areas, you can produce some very professional effects.
You can select the Epson Character Graphics set with your software or by setting DIP switch l-3 ON. For many applications it is best to use the DIP switch instead of the software command because the character graphics are then available as soon as you turn the printer on.
