Grayscale
Grayscale changes all the colors for the document you 
select into black, white, and shades of gray. Use this 
setting when you would like to print color documents in 
monochrome for speed or when color information is not 
important.
Fax Friendly 
Fax Friendly changes your color document to patterns of 
black and white. The different colors are rendered as 
distinguishable black and white patterns. For example, a 
pie chart which contains wedges of different solid colors 
will be printed with a different pattern replacing each 
color so that the distinction between the pieces is 
maintained. Color text is also rendered as a pattern, but 
the character is outlined. Anything that is black in your 
document remains black and is not rendered as a pattern.
Use Fax Friendly to print a color document in a black and 
white mode so that it can be used as a fax original or for 
black and white copying.
Fast Blue
Fast Blue prints a color document only in shades of blue 
(cyan) and black. All color text and images in the 
document are rendered in shades of blue while the text 
and images that were originally black remain black. The 
shades of blue maintain the distinction between parts of 
your document which were originally in different colors.
Use Fast Blue to print color documents at twice the speed 
of full color, while retaining more color information than 
when using Grayscale.
