[cups.development] Create a virtual postscript printer

[Joel Buckley]

Beat,

I would suggest you divide the problem into two parts:

1. Define a Postscript accepting software printer that accepts streams
   of Postscript print jobs, consistent with "gs".  This may include you
   building a PPD file directing the printing to direct printing to your
   program,  (CUPS folks should be able to help with the PPD file and
   how to add the printer to the CUPS service.)

2. Build a program of your choosing that takes 5-6 input parameters,
   again consistent with gs, and ships the postscript incoming document
   back to the calling user's client service as suggested below.

Cheers,
Joel.
