Unfortunately I know more about ps/pdf than I care to.
ps2pdf is a wrapper to ghostscript. Basically it just calls gs with
the output device set to "pdfwrite". The pdf format has 14 built-in
standard fonts, like Times, Arial, etc. If the postscript file
is using different fonts, then gs has to either embed the font into
the pdf, or turn it into bitmaps (ie pictures of characters).
If it creates bitmap fonts, it typically looks terrible in acroread
but barely noticeable if you use "gv" to view it (as gv also uses
ghostscript for rendering).
I think newer versions of gs are better - version 5.50 was widely
used but 6.x releases are out now with much improved pdf support.
(I think it is smarter in mapping fonts to the standard fonts).
Well, I managed to sum it up without mentioning Type1, PostScript
and Type3 fonts :)
