};
printClient.onError = (id: number, message: string) => {
    console.log("Print client error for action #", id, ": ", message);

    console.log("Print client connected action #: ", id);
    var message = "Print test String!";
    var bytes = [];
    for (var i = 0; i < message.length; i++) {
        var c = message.charCodeAt(i);
        bytes.push(c & 0xFF);
    }
    printClient.send(bytes);
};
printClient.onSent = (id: number) => {
    console.log("Print client sent action #: ", id);
    // When we are finished
