Two section in the manual (on disc):
1. In the Introduction
-------------------
Excellent print quality:
(a) ImageREt 2400 provides 2400 dpi color and laser-class quality
through a multilevel printing process.
(b) True 600 by 600 dots per inch (dpi) text and graphics.
2. In the Color (sic) chapter:
--------------------------
Image REt 2400 provides 2400 dots-per-inch (dpi) color laser-class
quality through a multi- level printing process. This process precisely
controls color by combining up to four colors within a single dot and by
varying the amount of toner in a given area. ImageREt 2400 has been
improved for this printer. The improvements offer trapping technologies,
greater control over dot placement, and more precise control of toner
quality in a dot. These new technologies, coupled with HP's multilevel
printing process, result in a 600-by-600 dpi printer that provides
2400-dpi color laser-class quality with millions of smooth colors. In
contrast, the single-level printing process found in the default mode of
other color laser printers does not allow the colors to be mixed within
a single dot. This process, called dithering, significantly hinders the
ability to create a wide range of colors without reduced sharpness or
visible dot structure.
What do you think this means?
