Current setting
The Current Setting sentence dynamically changes the word in quotation marks to reflect
the current PQ setting based upon the current choices in this dialog. The default is
“Custom” but can change to “Default” whenever the selections match those settings
(defined above).
Graphics settings
In the PCL 5c driver, there are four settings under Rendering Mode that control the way
in which the driver expresses a page:
• Automatic (Auto Mode), the default, will send pages as HP GL/2 unless you are
currently in an application which is found in one of the exception lists. In this case,
the rendering mode will depend on which exception list the application is found.
• Send Graphics as Vector uses HP GL/2 as the imaging model.
• Send Graphics as Raster uses PCL 5c raster mode as the imaging model.
• Send Page as Raster uses PCL 5c raster mode as the imaging model and images all
text as raster graphics without using downloaded or resident fonts.
Output Settings
Resolution
For PCL 6 and PCL 5c drivers, there is one setting: 600 dpi.
Ret
HP Color LaserJet 4550 printer does not support Resolution Enhancement Technology
(RET).
Scale Patterns (WYSIWYG)
This is implemented to address the moiré effect some applications can encounter with
certain types of patterns. This feature will allow you to turn off the pattern scaling that the
driver performs. What you will lose is WYSIWYG with patterns, but the printed result
might look better. This feature works only with programs that use vector hatch patterns.
This option is on by default.
Print all Text as Black
This is not selected by default. When selected, this option will cause the driver to image
all text as black regardless of the document’s text color settings except for white text,
which will remain white.
Gloss Print Finish
This is not selected by default. When selected this option applies a glossy finish to
documents that are printed on non-glossy paper. The gloss print option also improves
print quality when you are printing on rough or heavy media.
Font Settings
Send TrueType as Bitmaps is the only setting available and provides you a safety net for
applications that have trouble using TrueType fonts for special graphic purposes, such as
shading, rotation or slanting. This feature is also in place for backward compatibility
purposes. When Send Page as Raster is selected (in the PCL 5c driver only), Send True
Type as Bitmaps is not available. Using this feature allows TrueType fonts to be
converted to bitmap soft fonts before downloading.
When True Type as Bitmaps is unchecked, the driver sends True Type fonts to the
printer as outlines, which retain the standard format (Outline) of the fonts.
