Jaws PDF Courier seems to be getting further. Pelagon are using it as a basis for Web 2 Print, presented here as part of the Heidelberg approach. Positive Focus continue to offer ready4print. Apparently Global Graphics offer Courier as a software development kit so there are various ways that the job ticket information could be sent that relates to each PDF for copy. Some form of XML could be used so it should be possible to relate this to JDF. Maybe some requests from printers would encourage this.
