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
