Note that it works only if pdftops is compiled in the Ghostscript mode 
and Ghostscript 8.64 is used. Poppler's pdftops has a bug which prevents 
from printing documents with pages of different sizes 
(https://bugs.freedesktop.org/show_bug.cgi?id=19777). Ghostscript 8.63 
doe not produce completely DSC-conforming PostScript, which makes pstops 
not recognizing the paper size changes.
