1-2 System GuideGateway and Network ConfigurationJob Definition Format (JDF)This release of the Xerox FreeFlow ® Print Server introduces anew JDF Gateway.The JDF is a job ticket and workflow specification language. Itprovides the means to describe print jobs.The ability to support JDF job tickets with PDF data files addsflexibility when users want specific settings for jobs instead ofdefault queue settings.The benefit of this Gateway is that it processes the JDF job ticketsand returns updated JDF job tickets containing job statusinformation and the process times required.Technical OverviewJDF Gateway (JDFGW) processes the JDF job tickets and setsjob attributes accordingly for files to be printed. Upon receiving aJDF job ticket from Hot Folder (HF) Observer, JDF Gateway usesJDF Toolkit to process the ticket and submit the data fileassociated with the ticket to the FreeFlow Print Server to print.After each job submission to the FreeFlow Print Server, JDFGateway updates and outputs the JDF job ticket into a specific ordefault folder.The JDF ProcessReceive JDF Job Tickets from Hot FolderWhen a file is dropped in the Hot Folder, HF Observer checks ifthe file is a JDF job ticket. If it is, HF Observer will submit the ticketto JDFGW.Process JDF Job TicketsThe JDF Gateway is invoked to parse the ticket and create a JDFNode based on the ticket. JDF Toolkit then transforms the JDFNode into a Combined Digital Printing (CDP) Node.After a CDP Node is formed, the job attributes are converted intothe common CPSS representation.
