（electron vue3 项目搭建部分自行查找其他资源本文只讲解Electron+vue3 如何实现静默打印）

第一步获取打印机资源

渲染端代码（vue里面）

// 因使用了vite所以在浏览器中打开 require会报错 只能在electron中
const { ipcRenderer } = require( 'electron')
// 初始化打印
async function handleInit() {//  获取到当前所有打印机 （获取以后取打印机NAME 用于electron的deviceName字段）ipcRenderer.invoke("getPrinters").then(res=>{console.log(res)})// 创建要打印的窗口await ipcRenderer.invoke("openPrintWindow",'printId');
}

第二步进程端完善

在electron文件夹目录下新增文件print.ts

// print.ts 
import { app, BrowserWindow, shell, ipcMain, BrowserWindowConstructorOptions, WebContentsPrintOptions } from 'electron'export const electronPrint = () => {let win: BrowserWindow;// 获取系统打印机详情ipcMain.handle("getPrinters", async (event) => {return await event.sender.getPrintersAsync();});// 调用打印机打印ipcMain.handle("printHandlePrint",async (event, options: WebContentsPrintOptions) => {console.log("调用打印了")return new Promise((resolve) => {event.sender.print(options,(success: boolean, failureReason: string) => {console.log("打印的结果",{ success, failureReason })resolve({ success, failureReason });});});});// 创建打印界面ipcMain.handle("openPrintWindow", (_, id) => {// id 用于传递的参数openPrintWindow(id);});// 销毁打印界面ipcMain.handle("destroyPrintWindow", () => {if (win) win.destroy();});function openPrintWindow(id) {const otherWindowConfig: BrowserWindowConstructorOptions = {useContentSize: true,autoHideMenuBar: true,frame: false,show: false,webPreferences: {contextIsolation: false,nodeIntegration: true,webSecurity: false,// 如果是开发模式可以使用devToolsdevTools:true,// 在macos中启用橡皮动画scrollBounce: process.platform === "darwin",},};win = new BrowserWindow({titleBarStyle: "hidden",...Object.assign(otherWindowConfig, {}),});win.loadURL('http://localhost:5173/#/print');win.setMenu(null);win.on("ready-to-show", () => {console.log("打印窗口已经新建出来了  隐藏处理")win.hide();});win.on("closed", () => {win = null;});}
}

在main中调用即可

第三步渲染端（vue）调用打印

    onMounted(async()=>{const { ipcRenderer } = require( 'electron')setTimeout(async()=>{ try {await ipcRenderer.invoke("printHandlePrint", { deviceName:"Printer_POS_80",silent: true, // 静默打印pageSize:{width:'72100',height:'210000',},margins: { marginType: "printableArea" }, // 网页的边距});} catch (error) {} finally {await ipcRenderer.invoke("destroyPrintWindow"); // 打印完成销毁新窗口}},1000)})
