HP deskjet 600 User Manual

Specifies the HP typeface number of the font. Three versions of this field are used: the obso-
lete single-byte version for older fonts, the version used by HP DeskJet 500 and HP LaserJet
III printers, and the new HP LaserJet 4 version (also used by the HP DeskJet 600 and 85X
Series printers.

Single-Byte Version

HP DeskJets prior to HP DeskJet 500 and HP LaserJets prior to HP LaserJet IID used only the
least significant byte (LSB). These printers ignore the upper byte (MSB) in the current version
described below.

HP LaserJet III / HP DeskJet 500 Version

The typeface word includes a 4-bit field for the vendor number, a 2-bit field for the version
number, and a 9-bit field for the actual typeface number. The most significant bit of the most
significant byte is always zero. The typeface word is shown below.
