- "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.
