Rasterization
Each time the print engine is ready to print a new page, the print data is
translated into a bitmap format that is stored, and then read by the print
engine.
For monochrome printing, the page bitmaps consist of black bitmaps only.
Color printers translate the print data into either four separate bitmaps, (one
for cyan, one for magenta, one for yellow, and one for black) or a black
bitmap only for monochrome output.
The below illustration demonstrates the color rasterization process with
bitmap representations. The rasterizer processes the data into four bitmaps,
one for cyan, one for magenta, one for yellow, and one for black. The print
engine processes these bitmaps and fuses the four toner layers onto the
media to produce a printed output.
"#
Cyan combined with yellow produces green, cyan combined with
magenta produces blue, and yellow combined with magenta produces
red. Cyan, magenta, and yellow combined produce black. In our
example, the black is produced by fusing all four toner colors.

What’s a bitmap?
A bitmap is a graphic
representation of a page. All
characters and art represen-
tations are printed using tiny
dots.
