2-38 PCL/PS Settings
On * , Off
This setting affects the printout for black text on a page. Under most
circumstances it is preferable to leave this option set to 'On'.
If [On] is selected, black colors generated by applications are printed using only
100% black toner. This means that black text will not exhibit halftone patterns
(such as moiré patterns), and the color toner will not be misaligned since only one
toner color (black) is used. It also eliminates color bleed (the unintended
overlaying or blending of two adjacent colors when text is printed).

If [Off] is selected, you can print black text as four color black (using Cyan,
Magenta, Yellow, and Black toner) and using normal PostScript rendering. For
some jobs, it is preferable to turn this option 'Off' (for example, if the page includes
gradient fills that use black).
