I can give some general information.  For more information, contact the 
Adobe Developers Association (+1-415-961-4111) for programmer-oriented 
documentation, or the makers and sellers of Adobe fax printers (i.e. NEC
and Compaq) for product and pricing information.

Adobe fax is essentially a fax board which plugs into a PostScript printer,
and some extensions to the PostScript language to control the fax board.
By adding some reasonably simple commands to a printable PostScript language
file, you can have the fax printer send your job to any Group 3 fax 
machine, or to any Adobe fax printer.  When sending to a Group 3 fax 
machine, the PostScript interpreter rasterises the job at fax resolution,
eliminating the poor quality caused by scanning a paper original or by
conversion from 300 dpi laser printer resolution to 200 dpi fax resolution.

In addition, when one Adobe fax printer is sending to another, they can 
communicate with PostScript language data instead of Group 3 raster data.
This means that the fax message can print in colour, at full device 
resolution (up to 800 dpi), and on large paper sizes.  In addition, 
the PostScript language form of the job can be smaller than the raster form,
so that the phone call is faster and cheaper.

Since Adobe fax uses a fax modem in the printer, it is highly unlikely that 
your existing fax modem will be usable.  Also, only printers which have 
been designed with Adobe fax in mind can be upgraded to support it.  
Currently, the NEC SilentWriter 95 and 97, and the Compaq PageMarq 15 and 20 
are the only announced printers with Adobe fax capability.  NeXT 
workstations also use Display PostScript to rasterise faxes, but this is
slightly different than Adobe fax as described above.

Adobe has developed fax drivers for Macintoshes and PC's.  These provide
the PostScript language commands to enable fax printing from most 
applications.  I believe these drivers are shipped with the NEC and Compaq
