till.kamppeter> 

The pdftopdf filter inserts no PostScript code into the PDF data
stream. It only handles JCL options (such as JCLOpenUI) in the PPD file.
It should be defined how should we inserts (Job) options into the
PDF data stream. 

till.kamppeter> Ralph, can I simply preceed the PDF data stream with the PostScript code 
till.kamppeter> from the PPD, putting "%!PS-Adobe-3.1" at first, then the code of each 
till.kamppeter> option, and after that simply the PDF? Or how does it work?
