Why don't you just export the job done in your favorite design software as PDF? The layout module of Print Factory is quite powerfull, more powerfull than Flexis' or many other RIPs out there.
I don't know what the PF tehnician show to you but my workflow is this.
I allready have queues for different printers and print modes. I drag the PDF in the queue that I want to print and the layout open by it self. There I set the number of copys, arangement, cut (or not), tiling, other finishing and hit print. Imediately or to wait for my later command.
I have used Wasatch, Flexi, Onyx and PF is by far the best.
