• 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.
