求助！通信灯闪，但是不打印

打印机正常，用风火码小程序可以正常打印

用demo写数据，通信灯闪，但是不打印

console显示：发送完成 errCode:0 errMsg:writeBLECharacteristicValue:ok
这是报错吗？

无法打印中文字

我需要做一个打印收据的功能，需要能够打印英文的收据和中文的收据，参考你的代码打印出来还是一堆乱码

这是我用你的代码 打印出来的array buffer

我是编写vue.js 然后使用cordova转译成应用程序

打印机特征值一直返回false

下载您的demo后，成功的连接了打印机，但是在getBLEDeviceCharacteristics获取特征值的时候，
read
write
notify
indicate
全部返回的是false
经过测试打印机本身是没有问题的
