Print Enhancement Commands

The print enhancement commands enable your printer to improve or enhance the print quality. Print enhancements include such things as superscript and subscript text, text underlining and overscoring, and emphasized print to make the print appear bolder. The following paragraphs describe the print enhancement commands.

Select Expanded Print

Control character:	SO
Hexadecimal:	0E
Escape sequence:	ESC	SO
Hexadecimal:	1B	0E
Escape sequence:	ESC	W	SOH
Hexadecimal:	1B	57	01

These commands select the expanded (double-wide) print mode for either draft or LQ printing. A Carriage Return command (CR) cancels the expanded print mode; therefore, for two or more consecutive lines of expanded print you must invoke the Select Expanded Print command for each line.

Cancel Expanded Print

Control character.	DC4
Hexadecimal:	14
Escape sequence:	ESC	W	NUL
Hexadecimal:	1B	57	00

Select Compressed Print

Control character:	SI
Hexadecimal:	0F
Escape sequence:	ESC	SI
Hexadecimal:	1B	0F

These commands cause the printer to print characters at about 60 percent of their normal widths. For example, for a character pitch of 10 cpi, one inch of text contains about 17 characters instead of the normal 10.
