CmdRasterGraphicsResolution.java

/**
 * <b>Command ESC * t # R</b>
 * Raster graphics can be printed at various resolutions. This command
 * designates the resolution of subsequent raster data transfers in
 * dots-per inch.
 * 
 * <b>Default</b> = 75
 * <b>Range</b>   = 75, 100, 150, 200, 300, 600
 *
 * #   = 75 - 75 dots-per-inch
 * 		100 - 100 dots-per-inch
 * 		150 - 150 dots-per-inch
 * 		200 - 200 dots-per-inch
 * 		300 - 300 dots-per-inch
 * 		600 - 600 dots-per-inch
 * 
 * <b>Notes</b>
 * When configured for 300 dpi resolution, the printer automatically
 * expands raster graphics transferred at resolutions less than 300
 * dots-per-inch to 300 dots-per-inch during printing.
