Function: requestPrinters()

function requestPrinters(opts: ConnectOptions): Promise<Readonly<Record<string, PrinterAdapter>>>;

Unified browser-picker factory.

The LT-200B is single-engine and BLE-GATT-only, so this is a one-transport dispatch — the transport discriminator must be 'bluetooth-gatt'. Other values throw. Auto-identifies by service UUID prefix (DECISIONS.md D4); the LT_200B is the only candidate, so deviceKey is never required.

Returns a 1-key PrinterAdapterMap keyed by the device's primary engine role.
