＃全局安裝nw-gyp
npm install -g nw-gyp
＃設置目標NW.js版本
set npm_config_target=0.31.4
＃設置構建架構，ia32或x64，win10, osx為x64操作系統
set npm_config_arch=x64
set npm_config_runtime=node-webkit
set npm_config_build_from_source=true
set npm_config_node_gyp=C:\Users\NALA\AppData\Roaming\npm\node_modules\nw-gyp\bin\nw-gyp.js

#win10下還要設置python路徑：
set PYTHON=C:\Users\NALA\.windows-build-tools\python27\python.exe

最后 npm install —msvs_version=2015?
安裝編譯不成功，就多試幾次，刪除package-lock.json

const escpos = nw.require('escpos');
const device  = new escpos.USB();
const options = { encoding: 'GB18030'};
let printerList = escpos.USB.findPrinter();

const printer = new escpos.Printer(device, options);

console.log(printerList);
device.open(function(){
  printer
  .font('a')
  .align('ct')
  .style('bu')
  .size(1, 1)
  .text('The quick brown fox jumps over the lazy dog')
  .text('敏捷的棕色狐貍跳過懶狗')
  .barcode('1234567', 'EAN8')
  .qrimage('https://github.com/song940/node-escpos', function(err){
    this.cut();
    this.close();
  });
});
