It will be, but it will do nothing useful with high level output. BTW if 
you want to talk to us on IRC then its best to try European office hours

The PostScript output from the ps2write device is deliberately 
device-independent. That is it will not request device-dependent features 
(such as duplex). When the input is a PDF file it can't anyway, because PDF 
has no such features in the format.

If you want to add device-specific code to the output of ps2write you can 
use the PSDocOptions and PSPageOptions features. Anything added to the 
PSDocOptions will be emitted in the document setup portion of the 
PostScript program, and anything added to the PSPageOptions will be added 
to every page setup portion of the PostScript program.

This allows users to mimic the kind of setup often seen in output from 
PostScript drivers such as the Microsoft one. Eg:

[{%%BeginFeature: *MirrorPrint False
<</MirrorPrint false>> setpagedevice
%%EndFeature
} stopped cleartomark
