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

150 - 150 dots-per-inch

200 - 200 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.

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.
