HP 4 FAMILY - Manual (Page 155)

Both the typeface family value and the typeface base value
can be used for font selection. Since the typeface family
value (two-byte value) is based on the typeface base value
(9 bit value), a font selection which specifies the typeface
base value may select a font described by a typeface family
value in the printer.
There is some variation in how font selection occurs
between PCL 5 printer models when mixing the typeface
family and base values. The typeface selection compatibility
for two types of values is identified for the various PCL 5
printers in Table 3-8.
Some typeface (two-byte) family values and their
corresponding base values are listed below. For a complete
listing of typeface family and base values, refer to Tables
C-2 and C-3 in Appendix C of this document.
