HP LaserJet Emulation (Mode 6)

LaserJet Font Escape Sequences
The example below shows an HP font selection escape sequence that selects a LetterGot-
hic font with fixed-pitch, 12-cpi, 12-point, upright-style, normal stroke weight.
To select this LetterGothic font, send the following escape sequence to the printing sys-
tem:
ESC(8U ESC(s0P ESC(s12H ESC(s12V ESC(s0S ESC(s0B ESC(s4102T
Any escape sequence with two similar consecutive letters after the ESC parameter can be
combined as in the transformation of the LetterGothic font below:
ESC(8U ESC(s0p12h12v0s0b4102T
The FSET command of PRESCRIBE utilizes a similar font selection method. (The sym-
bol set selection is made with the CSET command.) Note the similarities in the FSET
command sequence below:
FSET 0p12h12v0s0b4102T;
Several other LaserJet codes should be considered for font management. See the Font
Management section of the HP LaseJetPrinter commands on page 56 and onwards.
LaserJet Symbol Sets
Symbol set has the highest priority in the HP font selection. The factory default symbol
set is IBM PC-8 (10U) for the LaserJet emulation. The LaserJet printer has many other
symbol sets not directly accessed by the INTL command. Temporary selection of one of
these symbol sets can be made with the CSET (Change symbol SET) command or from
the operator panel keys. You can also assign one of these symbol sets to a particular font
using the FSET (change current Font SETting) command. More information on these
commands appear in Chapter 4.
By giving a particular value for the FRPO U6 and U7 parameters, you can set one of the
HP symbol sets as the power-up symbol set. In general, symbol set value is:
(Escape sequence value field value × 32 + (Decimal value of escape sequence termina-
tion character – 64) [=(U7 – 50) × 100 + U6])
Symbol Sets for Bitmap Fonts
The printing system substitutes with a scalable font when a bitmap font is required for
downward compatibility. The following symbol sets are supported when substituted bit-
map fonts are in use. To power up the printing system in one of these symbol set, use the
following FRPO U6 and U7 values.

Pitch 12-cpi ESC(s12H
Height 12-point ESC(s12V
Style Upright ESC(s0S
