Dumb question: A while ago, my boss was supposed to provide a
document to a publisher, and the publisher specified that it was
supposed to be in "native" PDF, _not_ generated from PostScript. Is
there a way to do that? All the methods I know of getting to PDF
involve a PostScript interim step. At least, I assume methods like
PDFWriter use PostScript, even if it's not visible. True?

I hope you can clear this up for me.

P.S. I had trouble viewing PostScript files or printing partial
PostScript files until I downloaded GSView, a Windows front-end for
GhostScript. I recommend it to anyone who needs to view or print PS
files: it's intuitive in use and works beautifully.
