You have completely missed the point. Have a look at both ghostscript's and 
libpoppler's bug database: neither's support of PDF *1.4* is complete, and 
that's what, over 10 years old. And I hope you do not used either of them in 
any form. TeXLive/Evince/xpdf/kpdf/okular used the latter, and linux-based 
printing used the former.
