Usage

import * as React from "react";

import RNReactNativeZebraPrinter from "react-native-zebra-printer";

interface IProps {}

const PrinterExample: React.FC<IProps> = () => {
    const [printer, setPrinter] = React.useState<any | null>(null);

    React.useEffect(() => {
        connectPrinter();

        return () => {
            if (printer !== null) {
                RNReactNativeZebraPrinter.closeConnection();
            }
        };
    }, []);

    /**
     * Create a connection to the printer.
     */
    const connectPrinter = async () => {
        const devices = await RNReactNativeZebraPrinter.getBondedDevices();
        const printers = devices.filter((device: any) => device.class === 1664);
        const p = printers.length ? printers[0] : null;
        if (p === null) {
            console.warn("unable to find printer. Found devices:", devices);
        }

        setPrinter(p);

        RNReactNativeZebraPrinter.initConnection(p.id);
    };

    const print = () => {
        RNReactNativeZebraPrinter.print(
