Job Definition Format (JDF)
This release of the Xerox FreeFlow® Print Server introduces a
new JDF Gateway.
The JDF is a job ticket and workflow specification language. It
provides the means to describe print jobs.
The ability to support JDF job tickets with PDF data files adds
flexibility when users want specific settings for jobs instead of
default queue settings.
The benefit of this Gateway is that it processes the JDF job tickets
and returns updated JDF job tickets containing job status
information and the process times required.
Technical Overview
JDF Gateway (JDFGW) processes the JDF job tickets and sets
job attributes accordingly for files to be printed. Upon receiving a
JDF job ticket from Hot Folder (HF) Observer, JDF Gateway uses
JDF Toolkit to process the ticket and submit the data file
associated with the ticket to the FreeFlow Print Server to print.
After each job submission to the FreeFlow Print Server, JDF
Gateway updates and outputs the JDF job ticket into a specific or
default folder.
The JDF Process
Receive JDF Job Tickets from Hot Folder
When a file is dropped in the Hot Folder, HF Observer checks if
the file is a JDF job ticket. If it is, HF Observer will submit the ticket
to JDFGW.
Process JDF Job Tickets
The JDF Gateway is invoked to parse the ticket and create a JDF
Node based on the ticket. JDF Toolkit then transforms the JDF
Node into a Combined Digital Printing (CDP) Node.
After a CDP Node is formed, the job attributes are converted into
the common CPSS representation.
