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.
