Class: NetworkPrinterTransport

Defined in: server/peripherals/network-transport.ts:29

Raw TCP transport for network printers (port 9100 "JetDirect" printing). Construct, connect(), write() printer bytes from the shared encoder, close() when done. queryStatus() issues a DLE EOT real-time status query over the same socket.

queryStatus()

queryStatus(query?: "printer" | "offlineCause" | "paper"): Promise<PrinterStatus>;

Defined in: server/peripherals/network-transport.ts:157

DLE EOT real-time status. Some printers never answer — this resolves or rejects within statusTimeoutMs rather than hanging the caller. Concurrent calls are serialized: replies carry no correlation id, so only one query may be in flight per socket.
