Diffused:
When Diffused is selected, dots are placed to approximate source pixels . The
amount of "error" in the approximation is balanced with adjoining source pix-
els to better approximate the source image.

This option provides the same functionality as specifying the R macro.

Ordered:
Ordered dither places dots in a regular pattern to approximate the source pix-
el. A lighter source pixel is mapped to a pattern containing fewer pixels, while
a dense pattern is applied for dark pixels. This is the default option for color
and RTL printers.
