Comments:

You must open the printer before using this routine.

You specify the color you want by combinations of values showing the intensity of the three primary colors. For example, to get the colors in the following table, you set the RGB values as shown:

Color Red Green Blue
Red 255 0 0
Yellow 255 255 0
Green 0 255 0
Cyan 0 255 255
Blue 0 0 255
Magenta 255 0 255
White 255 255 255
Black 0 0 0

Some other, more unusual, colors are:

Color Red Green Blue
Dark orange 255 140 0
Navy blue 0 0 128
Violet 238 120 238
Beige 245 245 220

If your printer does not support color, it is up to the printer device driver to interpret these values. For example, some perform gray-shading; others choose either black or white for each color.
