8-4 PCL Font Selection EN
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:
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 Roman-8
Spacing Fixed
Pitch 10 cpi
Height 12 point
Style Upright
Stroke Weight Bold
Typeface Family Courier
Symbol Set Roman-8
