It is documented, but it's not part of the Adobe Type 1 font.  The .pfb
files are divided into chunks of data with a little header-descriptor on
each chunk.  This header is for the use of a PC-based downloader; it should
not be sent to the printer.

You can tell it's *NOT* PostScript because the first byte has value 80 hex,
which is not valid for Level 1 PostScript.  In Level 2, 0x80 it would be an
indicator of a "binary object sequence"--which is NOT what the .pfb is.

You need a downloader of some sort which will get rid of the funny little
headers.  You can NOT just send a .pfb straight to a printer.  (Well, you
can, but the printer will just complain.:-)

The header consists of:
	- 0x80: flag byte
	- type byte:  1=text, 2=binary data, 3=EOF
	- length: 4-byte little-endian integer counting the number of data
	  bytes which follow
