How endpoint discovery, transport, queue association, and device status create distinct HP connection states.
Connection has multiple meanings
A connection can mean a physical link, a network route, a discovered service, a protocol session, or a queue association. HP printer documentation and host status labels may use the word at different layers, so the layer must be named.
Endpoint and identity
An endpoint address or port describes where a host sends messages. Model identity describes what the device is. A queue can retain one while the other changes, which is why endpoint state and product identity should be recorded separately.
Protocol session and queue
A protocol can have its own reachability or session state, while a queue can be ready, paused, or unavailable in the host model. A device status signal can add another observation without replacing the host-side state.
Neutral state language
Use terms such as discovered, addressed, associated, reachable, session-active, or device-reported only when the emitting layer is known. This entry explains terminology without a connection checklist or fault diagnosis.

Questions and answers
Does a discovered HP printer have an active print session?
Not necessarily. Discovery and an active protocol or queue session are separate states.
Is a queue’s offline label a physical measurement?
It is a host-side summary and should not be treated as a complete physical diagnosis.
