Electron：如何将API响应的ZPLCode值直接打印到标签打印机？

我有一个电子应用程序，我正试图打印到标签打印机。我向外部API发出请求并得到响应：

ResponsePackage:[
0: {
  AirportCode: "",
  BarCode: "111111111111111111111111111111",
  PackageID: "xxxDEV1057-A",
  ShippingCharge: 0,
  TrackingNumber: "xxx000000380",
  Unicode: "40",
  ZPLCode: "~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the rest of the response code ...
 },
1: { .. another entry with similar format}
]

具有此响应的窗口中的相关代码具有以下代码：

      const options = {
        // name: 'ZDesigner GC420d (EPL)',
        silent: false,
        printBackground: false,
        color: false,
        margin: {
          marginType: 'printableArea'
        },
        landscape: false,
        pagesPerSheet: 1,
        collate: false,
        copies: 1
      }

      if (orderCreated) {
       responsePackage.map(puroPackage => ipcRenderer.send('print-job', [options, puroPackage.ZPLCode]) ) // ZLPCode is the code from the response object above
      }

在main.js文件中，我有对事件作出反应的icpMain：

 ipcMain.on('print-job', (event, args) => {
    console.log('args: ', args); // shows the proper ZPLCode passed in

    // how do I print the ZPLCode passed in args?
    mainWindow.webContents.print(args, (success, failureReason) => {
      if (!success) console.log(failureReason);

      console.log('Print initiated')
    })
  })

---

我不想打印主窗口的内容，因为ZPLCode数据不在窗口中，而只在内存中发送到标签打印机。如果ZPLCode不在窗口中，如何打印它的内容？

无需通过

ipcRenderer

和

ipcMain

进行通信，也无需使用

WebContent.print（）

，因为我没有打印窗口的内容

为了使其正常工作，我必须使用

warn

安装

node打印机

然后，我通过从“打印机”导入打印机，将打印机导入到我的模块中

使用控制台.log（'printer.getPrinters:'，printer.getPrinters（））

查看操作系统上安装了哪些打印机。我想使用的是名为'ZDesigner GC420d（EPL）'

然后，当我从外部API获得带有正确ZPLCode的响应时：

 // ResponsePackage is an array
        ResponsePackage.forEach(package => printer.printDirect({
          printer: 'ZDesigner GC420d (EPL)',
          data: package.ZPLCode,
          type: 'RAW',
          success: (jobID) => {
            console.log("sent to printer with ID: " + jobID);
          },
          error: (error) => console.log('error: ', error)
        }) )

      }

函数的作用是：只打印网页中的内容。因此，最好寻找其他模块。或者，如果可能的话，从json响应中创建一个新的临时html页面，并将其加载到一个新的browserwindow中，保持其show:false，然后尝试使用相同的newbrowserwindow.webcontents.print（）进行打印
