节点打印机无法在网络打印机中打印（node.js）

Question

I'm trying to send directly documents to my printer. I have used node-printer and have not error, but printer is not receiving anything. This is my code:

var printer = require("printer");
    filename = process.argv[2] || __filename;

console.log('platform:', process.platform);
console.log('default printer name: ' + (printer.getDefaultPrinterName() || 'is not defined on your computer'));
console.log('try to print file: ' + filename);

if( process.platform != 'win32') {
    printer.printFile({filename:filename,
    printer: process.env[3], 
    success:function(jobID){
       console.log("sent to printer with ID: "+jobID);
    },
    error:function(err){
       console.log(err);
    }
});

} else {
  var fs = require('fs');
  printer.printDirect({
    data:fs.readFileSync(filename).toString(),
    printer: process.env[3], 
    type: 'RAW',
    success:function(jobID){
      console.log("sent to printer with ID: "+jobID);
    },
    error:function(err){
      console.log(err);
    }
});

I test do "node print.js lorem.txt" and it looks like document is sent to print queue, but net printer is not receiving anything.

By the way, I'm working on Windows 10.

您正在使用printer: process.env[3]指定打印机，但由于要在控制台中写入printer.getDefaultPrinterName() ，因此您似乎要使用默认打印机，因此请尝试删除printer: process.env[3],并使模块在默认打印机中打印，然后查看是否可以解决您的问题。
