Previous Usage 
The previous treatment of the Typeface field supported the LaserJet 
IIP, IID and LaserJet III family printers. It consisted of the Typeface 
Least Significant Byte (LSB; the original, one-byte typeface value 
used prior to the LaserJet IID printer) and the Typeface Most 
Significant Byte (MSB) in the font header.
The previous typeface family value field is shown below. It included 
a 4-bit field to specify the vendor number, a 2-bit field for the version 
number, and a 9-bit field which contained the typeface base number. 
The most significant bit of the MSB was always zero.
Vendor-Version The Vendor-version (bits 10 and 9) value was from 0 
to 3. It changed when the vendor changed the width or design of the 
characters in a font.
