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:

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.
