ENWW Printer-Specific Differences 2-51
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.
