问题描述
任何人都知道如何为 node js 设置 USB 打印机.我无法为其配置接口.这是我的代码
Anyone knows how to set-up a USB printer for node js. I m not able to configure the interface for it . Here is my code
enter code here const ThermalPrinter = require("../node-thermal-printer").printer;
const Types = require("../node-thermal-printer").types;
const electron = typeof process !== 'undefined' && process.versions &&
!!process.versions.electron;
async function testConnection () {
let printer = new ThermalPrinter({
type: 'star',
interface: "Gold" //name of the printer
});
printer.print("hi");
let isConnected = await printer.isPrinterConnected()
console.log("Printer connected:", isConnected);
}
testConnection();
推荐答案
我跳出的错误是在你的界面上.如果您使用 USB 端口,我建议您首先进行打印共享,然后通过修改值interface"来配置您的节点终端打印机文件
The error that jumps out at me is in your interface. if you use a usb port I advise you to start by making a print sharing and then to configure your node-termal-printer file by modifying the value "interface"
首先进行打印机共享
first you do a printer sharing
您修改值interface";指明路径和共享打印机
you modify the value "interface" indicating the path and the shared printer
`interface: '//localhost/printer',`
