Select double-strike mode
EscG (27)(71) <1Bh><47h>
This command turns double-strike mode on. Subsequent text is printed with a bold stroke width.
LPRINT CHR$(27); CHR$(71); 'Turn double-strike printing mode on
Cancel double-strike mode
EscH (27)(72) <1Bh><48h>

LPRINT CHR$(27); CHR$(72); 'Turn double-strike printing mode off
Select / cancel double-width printing
EscWn (27)(87)n <1Bh><57h>n
This command turns double-width printing on or off.
If n is set to 1 subsequent text is printed using double-width characters. The line spacing setting is doubled.
If n is set to 0 subsequent text is printed using normal sized characters. The previous character pitch setting
is restored.
When you specify a value for n you may also use the character codes for '0' and '1' (48 and 49) instead of 0
and 1.
Only Esc W 0 can be used to cancel double-width printing mode set using the Esc W 1 instruction.
Esc W 0 cancels double-width printing mode set using the Esc W 1 instruction, the SO control code or the
Esc SO instruction.
LPRINT CHR$(27); CHR$(87); CHR$(1); 'Set double-width printing mode
Select single-line double-width printing (I)
SO (27) <0Eh>
This command turns double-width printing mode on for one line only. The subsequent line of text is printed
using double-width characters and with the line spacing setting doubled.
The following commands cancel double-width printing mode set using the SO control code: LF, FF, VT,
Esc W 0, DC4, and ESC @.
If the "auto LF" (automatic line feed) function has been turned on from the control panel, the carriage return
control code, CR, will also cancel double-width printing mode selected with the SO control code.
LPRINT CHR$(14); 'Set double-width printing mode for one line
Select single-line double-width printing (II)
EscSO (27)(14) <1Bh><03h>
This command turns double-width printing mode on for one line only. The subsequent line of text is printed
using double-width characters and with the line spacing setting doubled.
The following commands cancel double-width printing mode set using the SO escape sequence: LF, FF, VT,
Esc W 0, DC4, and ESC @.
If the "auto LF" (automatic line feed) function has been turned on from the control panel, the carriage return
control code, CR, will also cancel double-width printing mode selected with the Esc SO escape sequence.
This command functions exactly like the SO control code.
LPRINT CHR$(27); CHR$(14); 'Set double-width printing mode for one line
Cancel single-line double-width printing
DC4 (20) <14h>
This control code cancels single-line double-width mode set with the SO control code or with the Esc SO
escape sequence. Subsequent text is printed using normal sized characters.
The previous character pitch is restored.
LPRINT CHR$(20); 'Cancel enlarged character mode set with SO
