6-16 HP PCL Font Characteristics
UNDERLINE COMMAND
The Underline commands control automatic text underlining..
ESC&d#D Enable underline
Decimal:
027 038 100 # 068
Hex:
1B 26 64 # 44
#: 0 = Fixed position
3 = Floating position
ESC&d@ Disable underline
Once underlining is enabled, any positive horizontal movement causes an underline to be
drawn. Positive horizontal movement includes the printing of text and positive horizontal
cursor motion.
When fixed position underlining is enabled, the underline is drawn five dots below the
baseline and is three dots thick. The baseline is an imaginary dot row on which all of the
characters in a given line stand. When floating position underline is enabled, the underline
position is determined by the greatest underline distance below the baseline of all of the
fonts printed on the current line. The underline distance is defined in a font's descriptor (see
Section 9).
The factory default is underline disabled.
HPGL/2 FONT SELECTION
In addition to selecting fonts using the PCL font selection commands, fonts can also be
selected and printed in HPGL/2 mode using the following HPGL/2 commands. The
HPGL/2 font selection commands allow you to print text within vector graphic images.
Primary Font (FI)
FI
font_ID
[;]
This command allows any accessible font that has been assigned a
font ID
number to be
selected as the primary (standard) font (the font characteristics are assigned to the standard
font). The font must be assessible to the printer as either a resident font or a downloaded
font. To be selected, the font must have been previously assigned a font ID number in PCL
mode. Also, for scalable fonts, the FI command must be accompanied by an SD command
(standard font definition) specifying the font’s point size or pitch. When the printer
receives this command and the requested font is present, the primary font characteristics
are set to those of the requested font. If the selected font is proportionally spaced, the pitch
characteristic is not changed.
