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.

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.
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. illustrates how a
single bit is translated into the corresponding printed dots in various
graphics resolutions when the printer is configured for 300 dpi.
