Thank you, Michael. You were so right. I just didn't realize the solution was there. Also reading "For security reasons, CUPS will only run filters and backends that are owned by root and do not have world write permissions." in the documentation told me, that I shouldn't give 777 permissions to a backend.

My backend itself works now. But I can only write my postscript files to /tmp/***.ps :( Is it possible to write elsewhere? When I try to write to paths like /var/mypostscripts/ it gives me pstops failed error messages. Is there a list of allowed paths to write?

Thank you very much :)
