PostScript is far from dead. You would be banishing the entire publishing
industry if you say PostScript is dead :-)

Are you sure it hasn't been updated for so long? Take a look at the
PostScript 3 reference manual.

Implementing a full PDF parser is definitely much harder than a full
PostScript parser. PDF more or less encompasses PostScript.

PostScript is much more widely supported than PDF. It is just as
extensible as PDF as far as imaging goes.

Most printers are raster based at the core, except for certain plotters
(which are very interesting to watch BTW). Some printing solutions implement
the RIP in software on the host computer (such as Ghostscript or Adobe's
PressReady -- not sure if the latter has been deprecated by something
else). Others implement it on the printer itself, such as a few printers
in the HP LaserJet family.

More or less, most people are able to print PostScript on their printers
on most major operating systems.

As compared to PDF? In the context of the original poster's comment, what
did you have in mind for using plug-in filters? How is the PDF plug-in
support useful in any way with image representation?

The original poster was talking about color profiles.
