niimbot-web-print v1.2.3

精臣web打印websocket封装为promise

引入

npm install --save niimbot-web-print

使用

import { Socket, NMPrintSocket } form 'niimbot-web-print'

// 创建socket实例
const socketData = new Socket('ws://127.0.0.1:373989')
socketData.open((openBool) => {
    if (openBool) {
       // websocket连接成功  
    } else {
       // websocket连接失败
    }
})

// 创建打印实例
const nMPrintSocket = new NMPrintSocket(socketData)

// 获取打印机列表 支持以下两种写法
nMPrintSocket.getAllPrinters().then(res => {
   // res 打印socket消息方法数据
   console.log(res)
   if （res.resultAck.errorCode === 0) {
      nMPrintSocket.selectPrinter(res.resultAck.result[0], '1234').then(res2 => {
        console.log(res2)
      })
   }
})

const fn = async () => {
    try {
        const res = await nMPrintSocket.getAllPrinters()
        const res2 = await nMPrintSocket.selectPrinter(res.resultAck.result[0], '1234')
        console.log(res2)
    } catch (err) {
        console.log(err)
    } 
}
