You cannot add FFOM as a printer to FFC. In order to connect FFC to FFOM you should use the Save component and then configure prescripting in FFOM to pickup both the PDF and the print ticket.
Does Xerox have any scripts generated to do this, or does this script need to be written by the client. Seems to be functionallity that people would want.
We deliver this sort of thing either through your analyst or through the Solution Engagement Team (your account team can put you in touch with the SET).
Another option would be to use the external component in FFCore in conjunction with FreeFlow Print Manager. FFC would use the CLI interface for FFPrint Manager to submit the job to the printer.
