   How can I check that?

I don't know.  It was idle speculation.  Since then, i have
looked at stampa.ps as converted to a PNG via:

 gm convert stampa.ps stampa.png

and i see that the "half" that is cut off from the footer is the
*upper* half!  The footer text is clipped by the footer frame.
So that excludes incorrect bounding box problems (due perhaps to
improper paper size specification) in my mental model.  Also
supporting the theory that the paper size is indeed correctly
specified are the stampa.ps lines:

 %%DocumentMedia: A4 595 842 0 () ()
 %%PageMedia: A4

(where "A4" appears).  Thus, there must be something else going
on; paper size is a red herring...

Since i don't even have gv installed on this computer, it looks
like gv cannot be at fault, either.

So, the only thing left is the postscript itself must be wrong.
I see that in: 

 (setq ps-print-footer t
       ps-print-footer-frame nil
       ps-top-margin 18
       ps-bottom-margin 14
       ps-left-margin 12
       ps-right-margin 0
       ps-print-header nil
       ps-show-n-of-n nil
       ps-print-footer-frame nil
       ps-footer-lines 1
       ps-footer-offset 0)

the var ‘ps-print-footer-frame’ is set to nil (twice!), yet
stampa.ps line 217 obstinately reads:

 /PrintFooterFrame   true def

If you manually change the "true" to "false", then there is no
footer frame and thus there is no footer frame clipping.  So the
bug lies in the failure of the Emacs Lisp code to propagate the
Emacs Lisp variable ‘ps-print-footer-frame’ to the postscript
definition of ‘PrintFooterFrame’.  Or you could say, "one bug".
Maybe there are others.

But before you file a bug report, are you very sure that you
evaluated the ‘(setq ...)’ form *before* generating stampa.ps?
