HP LaserJet 4250/4350 Series - Software Technical Reference

Print All Text as Black
The Print All Text as Black feature is Disabled by default. When Enabled is selected, the driver
prints all text as black regardless of the original document text color. Color text is printed as black,
except for white text, which remains white. (White text is a reliable method of printing reverse
typeface against a dark background.) This setting does not affect graphic images on the page, nor
does it affect any text that is part of a graphic.
Send TrueType as Bitmap
NOTE The Send TrueType as Bitmap option is available only in the HP PCL 6 and HP
PCL 5e unidrivers. It is not available in the PS Emulation Unidriver.
Send True Type as Bitmap provides an alternative for those software programs that have trouble
using TrueType fonts for special graphic purposes such as shading, rotation, or slanting. The setting
is Disabled (off) by default. The TrueType fonts are first converted to bitmap soft fonts before
downloading. The Enabled setting causes the driver to send TrueType fonts to the printer as
outlines, which retains the standard format (outline) of the fonts.
REt
Resolution Enhancement technology (REt) refines the print quality of characters by smoothing out
jagged edges that can occur on the angles and curves of a printed image. It is On by default. Select
Off if graphics, particularly scanned images, are not printing clearly.
Alternative Letterhead Mode
Under normal operation, the product prints duplex jobs with a different orientation than single-sided
jobs. This becomes a problem when printing on letterhead, because the user has to switch the
orientation of the letterhead media if they need to go back and forth between duplex and single-sided
jobs. Alternative letterhead mode solves this problem.
When this feature is selected, you can load letterhead or pre-printed paper in the same way for all
print jobs, whether you are printing duplex or single-sided jobs. To use it, load the paper as you
would for a duplex letterhead job. (This is the exact opposite of how you would load the paper for a
single-sided letterhead job. See the User Guide for details.) If the printer tray has an icon that
indicates to load the paper either face-up or face-down, load the paper the opposite direction from
the orientation that is shown. When Alternative Letterhead Mode is on, both single-sided and
double-sided jobs will print the correct way, without having to change the orientation of the letterhead
or pre-printed media.
Graphics Mode
NOTE The Graphics Mode option is available only in the HP PCL 5e Unidriver. It is not
available in the HP PCL 6 and HP PS emulation unidrivers.
Use the Graphics Mode feature to select one of the following settings:
■ Send Graphics as Vector. Select this setting to send graphics to the product as a combination
of HP Graphics Language, V2 (HP-GL/2) and raster images. This setting might produce higher-
qualtiy output.
■ Send Graphics as Raster. Select this setting to send all graphics to the product as images
composed of individual dots. This setting might improve printing speed in some cases.
