Can't fetch printer status for Usb device

[saitahmety]

Using a usb printer adapter and trying to fetch the status of the printer.

"escpos": "^3.0.0-alpha.6",
"escpos-usb": "^3.0.0-alpha.4",

Here is my code creating the printer:

  const device = new escpos.USB(idVendor, idProduct);
  const options = {
    encoding: "cp857",
  };
  const printer = new escpos.Printer(device, options);

Here is the code:

  printer.getStatuses((status) => {
    console.log('status: ', status);
    console.log("status json: ", status.toJSON());
  });

This fails:

TypeError: this.adapter.read is not a function
