Sending PS instead of PDF from an OSX client

[Pippo Lacoca]

Hi

I am not sure if it is the better place to ask it, anyway i'd like to know if it is possible to tell an OSX client using a remote browsed printer from an UNIX CUPS server to send PS instead of PDF to the server.
We are having some issues with pdftops on the cups server (badly orientated pages, printer interpreter elaborating forever and so on) and those problems never rise when the stream coming to the cups server is postscript one (i.e. windows clients or printer directly connected to OSX cups via ipp).
