Character Enhancements
The HP LaserJet 4PJ printer supports PCL pseudo-bold
and pseudo-italic character enhancements. These
enhancements can be applied to the internal MS-Mincho
and MS-Gothic fonts. They can also be applied to a
TrueType soft font if a suitable “Character Enhancement”
Segment is downloaded with the font header.
The enhancements are selected using PCL font selection
commands. The pseudo-italic enhancement can be selected
using the Style command. The pseudo-bold enhancement
can be selected using the Stroke Weight command. The bold
levels which can be applied to the internal MS-Mincho and
MS-Gothic fonts are Semi Bold, Demi Bold, Bold, and Extra
Bold. For example, to select a 10-point, Extra Bold, Italic,
MS-Mincho font, use the following PCL command:
? (19K ? (s1p10v1s4b28752T
In the above command, Italics style (1s) and Extra Bold
weight (4b) are selected. Since there is not an Extra Bold
Italic MS-Mincho font resident in the printer, pseudo-italics
and pseudo-bolding algorithms are applied to characters
printed from the regular MS-Mincho font.
If a soft font is selected using the “Font Selection by ID”
command (e.g. ?(#X ), the font is selected without any
character enhancements applied. To select a soft font by ID
with character enhancements, first select the font by ID,
then select the desired attributes. For example, assume a
soft font is downloaded with ID = 1 and a Character
Enhancement Segment indicating that pseudo-bold and
pseudo-italics character enhancements can be applied. The
following command can be used to select that font with
those enhancements:
? (1X ? (s1s3B
Other font effects, such as character shadowing, strike-
through, and gray-shading can be accomplished using the
print model.
