	"PostScript is designed to be "device independent"--you're not
	supposed to CARE where your document's going."

Yes and no.  You are able to write device independent PostScript code,
if you assume a page size.  But the interrogation features of
PostScript, when used with a bidirectional communication port, can make
the user's life a lot easier.  For example, I have seen helpful
applications that know whether the destination printer handles color,
and disables the select-color commands if not.  This sort of immediate
feedback can help decrease the number of the user's misconceptions.

Macintosh users take this sort of thing for granted, because AppleTalk
is bidirectional.  IBM PC users do not, because the typical parallel
port is unidirectional.
