FFCore officially supports 1GB and smaller files. One can submit a larger file, it may or may not work. As for size limitations on various DFEs/printers, I do not know what they would be. I assume this would be a spool size limitation on the DFE.
I would like to know the maximum file size which i can submit for a job from Free Flow Core to Versant printer. When i submit a 400 MB pdf file, job is submitted successfully to the printer. But when i submit 1.7 GB or 2 GB pdf file, job fails immediately with "Printer cannot be reached" as job status. Is there any limit on the job size that can be sent to hold queue in a Xerox printer. I noticed similar behaviour in other production printers and Altalink printers as well.
