HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part I

11-20 Soft Font Creation EN
Bitmap Font - Unsupported values invalidate font creation.
Scalable Font - set to zero.
Note Hewlett-Packard recommends that bitmap soft fonts be designed in
portrait (0°), using the paper motion and raster scan direction of
the HP LaserJet Plus and LaserJet series II printers. The HP LaserJet
IID, IIP, 2000, and PCL 5 LaserJet printers rotate the fonts to match
the paper’s physical coordinate system for the various paper sizes.
Spacing (B)
Specifies the spacing of the font. A value of zero (0) specifies fixed
spacing and one (1) specifies proportional spacing.
Symbol Set (UI)
Specifies the symbol set for the font. This value is computed by taking
the value of the value field for the symbol set, multiplying it by 32,
adding the decimal (ASCII) value of the termination character (the
symbol set ID character value) of the escape sequence, and
subtracting 64.
For example, to compute the value for the ASCII (ISO-6) symbol set
(Value =
0, ID = U):
0U = (0×32) + (85–64) = 21
The legal range of symbol set escape sequence field values is 0 to
2047. Refer to Appendix C in the PCL 5 Comparison Guide for the
HP defined symbol set values for use in the font header.
HP reserves the right to define the symbol set escape sequence
value field values of 0 to 1023. Symbol set escape sequence value
field values 1024 to 2047 are available for use by independent font
vendors.
