Using Fonts - HP PCL 5 Reference Manual

Font Select Table
The initial font specification in a job should be made using all of the
font characteristics.
To select a Roman-8, fixed-spaced, 10 pitch, 12 point, upright, bold,
Courier font, for the current page orientation, specify each of the
characteristics using font selection escape sequences. Once the
characteristics have been specified, the font select table appears as
follows:
Symbol Set
Spacing
Pitch
Height
Style
Stroke Weight
Typeface Family
To subsequently select a font with the same characteristics differing
only in one aspect, only the single characteristic must be specified.
For example, to select a font differing only in stroke weight (in this
case, medium rather than bold), the printer's font select table could be
changed as follows:
Symbol Set
Spacing
Pitch
Height
Style
Stroke Weight
Typeface Family
