Function: requestPrinter()

function requestPrinter(options?: RequestPrinterOptions): Promise<PairResult>;

Open the browser BLE picker, pair with an LT-200B, and resolve the GATT service / characteristics. Returns the printer adapter plus diagnostic plumbing (observed UUIDs, best-effort link MTU).

Discovery derives TX / RX / aux UUIDs from the observed service-tail rather than requesting canonical UUIDs (DECISIONS.md D4). This is why WebBluetoothTransport.request() doesn't fit — it asks for characteristics by canonical UUID before it sees the actual service tail; we resolve + derive here, then wrap via WebBluetoothTransport.fromCharacteristics().

Parameters

Parameter	Type
options?	RequestPrinterOptions

Returns

Promise<PairResult>

Deprecated

For harness use, prefer requestPrinters({ transport: 'bluetooth-gatt' }). requestPrinter() is retained as the BLE-debug escape hatch (carries observed UUIDs / link MTU for the debug app).
