WiFiLabel~HS: Host Status (ZPL)
Asks the printer for a three-line host status snapshot.
Host status returns a short machine-readable snapshot: paper, pause, label length, buffer flags, head and ribbon state, and a few counters. The reply is three comma-separated records, each wrapped in start-of-text and end-of-text bytes, then a carriage return and line feed. It does not change settings. Send it any time you need to know why a printer is idle or why a label did not move. Parsers in this library accept a partial reply. Missing lines leave the matching flags false instead of failing the whole read.
