System software and job flow
This section describes how the system software processes are
used as a typical job flows through the system.
NOTE: There are no job flow differences between the High
volume printer and the Production publisher configurations.

Job
The job and the job ticket (if applicable) are received from the
network by one of the protocol gateways.
Input queue
The Job Pool Manager (JPM) process transfers the job into the
input queue. The virtual printer name and job attributes are
attached to the job. The job remains in the Input Queue until it can
be printed; for example, “held” and “faulted” jobs reside in the
input queue.
Decomposer
The Job Chooser reconciles the job attributes with the virtual
printer attributes. Once the job is ready for print, the Job Chooser
gives the job to the appropriate decomposer, PostScript or PCL.
