EscWn (27)(87)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$(1); 'Set double-width printing mode
Select single-line double-width printing (I)
SO (27)
This command turns double-width printing mode on for one line only. The subsequent line of text is printed
using double-width characters and with the line spacing setting doubled.
The following commands cancel double-width printing mode set using the SO control code: LF, FF, VT,
Esc W 0, DC4, and ESC @.
If the "auto LF" (automatic line feed) function has been turned on from the control panel, the carriage return
control code, CR, will also cancel double-width printing mode selected with the SO control code.
LPRINT CHR$(14); 'Set double-width printing mode for one line
Select single-line double-width printing (II)
EscSO (27)(14)
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
