Epson printer behavior and state reference

A component-by-component vocabulary for Epson queues, renderers, ports, protocols, and device status.
Name the reporting layer
A queue can report job state, a port can report delivery state, a renderer can report processing state, and the device can report status. An Epson status label has meaning only when its source component is known.
Behavior is not a single state
Behavior describes what a component does with a request; state describes its current condition. A queue may hold a job while the protocol session changes, and those are concurrent but different observations.
Capability and output context
The selected package and protocol determine how jobs and options are represented. Device status can add information about a physical resource, but it does not replace queue or renderer state.
Reference language
Use precise terms such as queued, rendered, transmitted, acknowledged, device-reported, or unavailable only with their layer. This page explains Epson state vocabulary without diagnosing a fault or giving corrective actions.

Questions and answers
Does an Epson queue state describe the device directly?
Not always. It describes a host object and may be supplemented by protocol or device status.
Can two layers show different states at once?
Yes. A queued job, a protocol session, and a device report are related observations with separate state machines.
