Package: gs
Version: 8.62.dfsg.1-3.2lenny5
Severity: normal


Hello,

gs ignores -dDuplex option when using
pswrite/psmono/pdfwrite output drivers, i.e. it
doesn't insert /Duplex true pagedevice entry:
> xrgtn@ux230p:/tmp$ cat hello.ps world.ps 
> %!PS
> /Courier 30 selectfont
> 100 400 moveto
> (|-|3110, ) show
> showpage
> %!PS
> /Courier 30 selectfont
> 100 400 moveto
> (\\/\\/0R1d!) show

So when I need /Duplex, I'm forced to generate
.pdf instead of .ps and then convert .pdf back
to .ps via pstopdf (libpoppler):
> xrgtn@ux230p:/tmp$ gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=o.pdf -q hello.ps world.ps
> xrgtn@ux230p:/tmp$ pdftops -duplex o.pdf o.ps
> xrgtn@ux230p:/tmp$ grep -i duplex o.ps
>       { /Duplex true def } if
> xrgtn@ux230p:/tmp$

I believe that is by design, as the docs [1] only cover -dDuplex for IJS and 
Windows output devices.
