process.
1. Job: The job and the job ticket (if applicable) are received from
the network by one of the protocol gateways.
2. 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.

Queue until it can be printed; for example, “held” and “faulted”
jobs reside in the input queue.
3. Decomposer: The Job Chooser (DC process) 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 (ps_cdf process, pcl_cdf process).

4. Output queue: After decomposition, the job is stored in the
output queue.
5. Printer: The marker (marker process) transfers the job from
the Output Queue to the Image Output Terminal (IOT or
