Question

我正在尝试使用usb接口从我的cordova应用程序打印到bixolon srp-350iii热敏打印机。

我的BixolonPrint.java包含以下内容：

case BixolonPrinter.MESSAGE_USB_DEVICE_SET:
Log.d(TAG, "perform mHandler: MESSAGE_USB_DEVICE_SET");
if (msg.obj == null) {
    BixolonPrint.this.cbContext.error("USB printer not found");

} else {
    //connect printer

}

这是我的index.html

        <script>
        function PrintThisData(elmnt,clr) {
            elmnt.style.color = clr;

            // compose text
            cordova.plugins.bixolonPrint.addLine({
                text: "This is a test message. Jing Yeng\r\n",
                textAlign: cordova.plugins.bixolonPrint.TextAlign.CENTER,
                fontStyle: cordova.plugins.bixolonPrint.FontStyle.BOLD
            });
            cordova.plugins.bixolonPrint.addHr();
            cordova.plugins.bixolonPrint.addLine("#@*èòçìàé€");
            // finally print
            cordova.plugins.bixolonPrint.printText(
                function (response) {
                    alert("Ticket printed successfully. Press OK to proceed!")
                },
                function (error) {
                    alert("Failed: " + error)
                },
                {
                    codePage: cordova.plugins.bixolonPrint.CodePage.CP_1252_LATIN1
                }
            );
        }
        </script>


        </div>

        <script type="text/javascript" src="cordova.js"></script>
        <script type="text/javascript" src="js/index.js"></script>
    </body>
</html>

在我的设备上安装生成的apk后，我无法从运行android 4.4的Android设备中检测到打印机。打印机已经使用usb连接到Android设备。

这可能是什么问题？
