CmdSpacing.java

/**
 * <b>Command Esc ( s # P</b>
 * Inter-character spacing can be specified as either proportional or fixed.
 * 
 * # = 	0 - Fixed spacing
 * 		1 - Proportional spacing
 * 
 * Default = 4099, Body Text
 * Range = 0, 1 (values outside the range are ignored)
 * 
 * <b>Notes</b>
 * When proportional spacing is specified and a proportionally-spaced
 * font is not available (in the requested symbol set), a fixed pitch font
 * with the current pitch specification is selected. If fixed spacing is
 * specified but is not available, a proportional-spaced font is selected
 * and the pitch characteristic is ignored.
