The choices of Color Map under each are Screen Match and Vivid. The Halftone setting
controls the selection of a halftone algorithm embedded in the firmware. The choices for
Halftone under each are Detail (the default for Text) and Smooth (the default for Graphics
and Photographs).
There is no requirement that the settings identified by a single string for color map or
halftone select the same physical output characteristic, but similarly named selections
create similar results. For example, Detail for text need not select the same halftone as
Detail for graphics. The available settings for all object types (text, raster, and vector) are
the same for both Color Map and Halftone. Those settings are listed below:

NOTE: The settings for text, graphics, and photos are overridden in the
PCL 5c driver if the Rendering Mode (Print Quality Details) is set
to Page as Raster or Graphics as Raster.
Print in grayscale
When selected, this control causes all printed output to be printed in grayscale. The
default setting is off. The driver communicates to the firmware to print in grayscale.
The halftone for grayscale printing follows the standard ColorSmart selections.
To test Print in Grayscale, print a color photograph in the default setting and then print it
in Print in Grayscale. The photograph printed in grayscale should also print as a single
color-plane (using only black, without spending time to render additional color planes on
the paper).
Visually compare the two with a copy of the same image printed on a monochrome laser
printer at the same resolution. Visible dithering will usually be present on the
monochrome laser's output, more prominently in and around areas of highlights. This
visible dithering should not be present on the grayscale output from the color device.
HP Color LaserJet 4550 printer quick sets
The state of this user-interface control is maintained via the existing HP Color LaserJet
4550 printer driver Quick Set. When this option is selected, the Quick Set name changes
to Untitled.
Configure tab features
The Configure tab lets you tell the driver about the hardware configuration of the printer. To set
up this page if bidi is enabled and working properly, click the “Update Now” button.
This tab is on top when you open the driver from the Printers folder by selecting Properties. When
you open the driver from within a program, the Configure tab will not be visible, with a few
