检查此节点程序包。https://www.npmjs.com/package/zuzel-printer

var Printer = require('zuzel-printer');
// Get available printers list
Printer.list();

这非常简单。您将得到如下所示的打印机列表

window.webContents.getPrintersAsync().then((data) => {
    // data will be an array of printer objects
}).catch((e) => {
    // handle error here
})

它将返回一个promise。以前使用的是getPrinters()方法，但现在已弃用。请参考官方文档

如果以Windows计算机为目标，则可以使用winreg程序包在注册表中搜索打印机。所有本地打印机都可以在
HKEY_LOCAL_MACHINE | SYSTEM | CurrentControlSet | Control | Print | Printers
中的网络打印机
HKEY_LOCAL_MACHINE | SYSTEM | CurrentControlSet | Control | Print | Providers | LanMan Print Services | servers | printers
