Function: requestPrinters()

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

Unified browser-picker factory for the labelwriter driver family.

LabelWriter devices are USB-only — the registry declares no other transports. Non-USB transports throw immediately.

USB path: opens the picker, auto-identifies via VID/PID against the registry. Composite devices (LW 450 Duo) get one transport per engine (label on IF 0, tape on IF 1) so the returned PrinterAdapterMap has one entry per engine role. Single-engine devices return a 1-key map.

Throws DeviceIdentificationRequiredError (with USB-capable candidates + a continueWith closure reusing the picked USBDevice) when the picked device's VID/PID is not in the labelwriter registry.
