Print spooler and queue model reference
How the spooler, queues, print processors, renderers, and ports divide responsibility in a print path.
Spooler as coordinator
The print spooler coordinates job submission, queue ordering, persistence, and handoff to the selected print path. It is a host service, not a printer driver and not the physical device.
Queue and processor
A queue holds jobs and printer association metadata. A print processor can interpret job data or prepare it for a rendering path, while a renderer creates the representation understood by the printer. These components have different contracts.
Port and device boundary
A port or protocol component delivers rendered data toward an endpoint. The device can report status independently. A spooler state, port state, and device state can therefore differ without contradiction.
Reading queue records
Useful fields include queue identity, job identity, renderer or processor, port, protocol, package, and device report. This reference explains architecture only and does not include spooler commands, repair actions, or fault diagnosis.

Questions and answers
Is the spooler the same as the print queue?
No. The spooler is a host service that coordinates queues and job flow; a queue is one managed printer object.
Does a spooler state describe the printer hardware?
Not directly. Device status is a separate signal in the overall path.
