Steps
Send requests to http://<host>:3344/printer/api/<slug> with query parameters a=<action> and data=<url-escaped JSON>.
Authenticate by sending the API key as the x-api-key header rather than as an apikey query parameter, per the vendor's own recommendation.
Use action commands scoped to a specific printer slug to query printer/job state or issue control actions.
For live/event-driven updates, connect over the server's WebSocket interface instead of polling REST actions repeatedly.
Known gotchas
All data and files must be UTF-8 encoded — using other encodings can cause unpredictable server behavior per the vendor's own documentation.
GET requests work for simple calls, but the vendor recommends POST once the data payload grows, since query-string length limits can affect large JSON payloads.
