Raster Graphics Resolution Command

Raster graphics can be printed at various resolutions. This command designates the resolution of subsequent raster data transfers in dots per inch.

?* t # R

# = 75	-	75 dots-per-inch
100	-	100 dots-per-inch
200	-	200 dots-per-inch
150	-	150 dots-per-inch
300	-	300 dots-per-inch
600	-	600 dots-per-inch
Default	=	75
Range	=	75, 100, 150, 200, 300, 600

	This command must be sent prior to the start graphics command. The
	factory default resolution is 75 dots-per-inch.
Note	Lower resolution graphics occupy less user memory. For example, the
	number of bits required to represent a two-inch by three-inch image at
	75 dots-per-inch is 33,750. The same image at 300 dots-per-inch
	requires 540,000 bits. Note that lower resolution graphics may not
	give acceptable print quality.

When configured for 300 dpi resolution, the printer automatically expands raster graphics transferred at resolutions less than

300dots-per-inch to 300 dots-per-inch during printing. Figure 6-2 illustrates how a single bit is translated into the corresponding printed dots in various graphics resolutions when the printer is configured for

300dpi.
