Define a "PDF printer". What's that? 

1/ A physical device (printer) with physical PDF interpreter on it (PDF 
add-on card)? 

2/ A physical device (printer) with logical PDF interpreter on it 
(software that runs the convertion)? 

3/ A software device (virtual printer) with logical PDF interpreter on it 
(code that runs the convertion)?

Because until now I have not seen a thing like "1/" and PostScript 
printer modules are truly costly (it can take up to $200/300) :-)

No, of course, me neither. 

But what I wouldn't like to see is a moving to PDF just because the sake 
of moving to something more manageable without having into account 
technical reasons but simplicity and force-joining (that is, "if CUPS -
owned by Apple- moves on PDF, linux will follow without questioning the 
pros and cons"). I would like to see, now more than ever, less 
"dependency" on CUPS (by "dependency" I mean here that it would be nice 
to have different alternatives as powerful as CUPS).

Well, I still can't speak on pdftopdf because is too new (there you have 
a "con") and not present in my system while pstops is:

sm01@stt008:~$ locate pstops
/etc/cups/oopstops.convs
/etc/cups/oopstops.types
/usr/lib/cups/filter/oopstops
/usr/lib/cups/filter/pstops
sm01@stt008:~$ locate pdftopdf
sm01@stt008:~$
