[cups] PPD's-less Postscript Duplex printing

[Helge Blischke]

As there is a bunch of different report generators around at Oracle  
(even Java based), and your installation seems not to be
the most recent one, please post (o e-mail to me to helgeblischke at  
web dot de) a sample PS file. After looking into that,
I probably can give you advice on how to implement the duplex printing.

By the way, actually Oracle's report generators should offer duplex  
printing by option (either by menus or via command line).
