Specification:

Type 42 is a PostScript font format used to download TrueType fonts to
PostScript interpreters which contain a TrueType rasterizer. A TrueType font
is first converted to a Type 42 format font and then read by a PostScript
interpreter. Type 42 yields better result than if a TrueType font is
converted to the Adobe Type 1 or Type 3 font formats.

The specification for the Type 42 font format is:
