true enough.  One can sort of find the info, but it is not really totaly reliable
because it can be changed by the user, but if you characterize a list of machines
as to their rendering modes, and then look the printer name up, you can
indirectly obtain this info.  It is *NOT* inherent in either the printer or
the lanuage, short of peeking into the roms.  Indeed, there are some very
fundamental reasons to need the knowlege of whether it is a black-writer
vs a white-writer.  Due to the the techniques used, a blackwriter has 
more resolution on fine detail, and a white writer can lose single pixels.
one often needs to alter a screen, for example, darken it for a white-writer
etc.  Currently the only solution seems to be the name lookup, provided
someone has not changed it.

Cheers
