[long snip]

Thanks for the detailed example. I will try it.
There is a cupsPreFilter option mentioned in the referred docoument:

http://cups.org/documentation.php/doc-1.5/spec-ppd.html#cupsPreFilter

"The pre-filter program will be inserted in the conversion chain immediately before the filter that accepts the given MIME type."

Have you only missed this one or it cannot be used?

I will give a try to this first.

Thanks,

Istvan
