In double-strike mode, the printer prints each character twice, the second time slightly below the first, making the text bolder. For even greater boldness, you can combine emphasized and double-strike. (Double-strike cannot be combined with NLQ mode, however.)

Italic printing

You can use italic characters for special emphasis or as an alternative typeface. ESC 4 turns on the italic mode even if the current DIP switch setting is set to the Epson Extended Graphics character table.

This sentence is in italics.

Underlining

The underline mode automatically underlines any piece of text. It underlines spaces, subscripts, and superscripts. (The printer does not, however, underline horizontal tabs.)

Superscripts and subscripts

Superscripts and subscripts can be used for printing footnote numbers and mathematical formulas. The example below combines underlining, superscripts, and subscripts in a mathematical formula.

Selecting typestyles with Master Select

Your printer has a special command called Master Select that allows you to choose many possible combinations of nine different modes. To send Master Select codes to the printer, you must first choose the mode combination you want. The modes you can choose from are 10 cpi, 12 cpi, proportional, condensed, emphasized, double-strike, double-wide, italics, and underline.
