where:	If the emulation is set at 10 cpi, it is set to 5 cpi.
	If the emulation is set at 12 cpi, it is set to 6 cpi.
	If the emulation is set at 17.1 cpi, it is set to 8.55 cpi.
Comment	This expanded print control code is a line-by-line print attribute;
	when the SO control code is received, the current line is printed
	double wide and automatically reset.
	This control code can be reset by a paper motion control code
	(LF, VT, CR, etc.), by the DC4 (double wide cancel) code, CAN
	or ESC W (double wide print). When set by SO, double wide
	print is not cancelled by the Autowrap feature.
Example	The following sample illustrates Expanded Print for one line only.
	Another example of expanded printing is shown for “Expanded
	(Double Wide) Print,” ESC W on page 129.
