前言
electron+vuecli3 实现设置打印机,静默打印小票功能
网上相关的资料比较少,这里给大家分享一下,希望大家可以少踩一些坑
github地址
必须要强调一下的是electron的版本必须是3.0.0不能,我尝试了4和5都没有实现
效果图
使用
git clone https://github.com/sunnie1992/electron-vue-print-demo.git npm install npm run electron:serve
实现
操作思路
1.用户点击打印
2.查询本地electron-store(用来向本地存储,读取数据)是否存打印机名称
3.已经设置,直接打印
4.没有设置,弹出设置打印机框
5.用户设置好确认后打印
首页App.vue引入了两个组件,一个是主动设置打印机的弹出printDialog
另外一个是打印组件,打印是通过webview将需要打印的内容渲染到html页面然后就能打印了
<template> <div id="app"> <el-button type="primary" @click="showPrint">设置打印机</el-button> <printDialog :dialog-visible="dialogVisible" @cancel="handlePrintDialogCancel" /> <pinter ref="print" :html-data="HtmlData"></pinter> <el-table :data="tableData" style="width: 100%"> <el-table-column prop="date" label="日期" width="180" column-key="date"> </el-table-column> <el-table-column prop="name" label="姓名" width="180"> </el-table-column> <el-table-column prop="address" label="地址"> </el-table-column> <el-table-column label="操作"> <template slot-scope="scope"> <el-button type="primary" @click="doPrint(scope.row)">打印</el-button> </template> </el-table-column> </el-table> </div> </template> <script> import { ipcRenderer } from 'electron' import printDialog from './components/PrintDialog.vue' import Pinter from './components/pinter.vue' export default { name: 'App', components: { Pinter, printDialog }, data() { return { dialogVisible: false, HtmlData: '', printList: [], tableData: [{ date: '2016-05-02', name: '我是小仙女', address: '上海市浦东新区', tag: '家' }, { date: '2016-05-04', name: '我是小仙女1', address: '上海市浦东新区', tag: '公司' }, { date: '2016-05-01', name: '我是小仙女2', address: '上海市浦东新区', tag: '家' }, { date: '2016-05-03', name: '我是小仙女3', address: '上海市浦东新区', tag: '公司' }] } }, mounted() { }, methods: { showPrint() { this.dialogVisible = true }, handlePrintDialogCancel() { this.dialogVisible = false }, doPrint(row) { this.HtmlData = row.name this.$refs.print.print(row.name) } } } </script> <style> #app { font-family: 'Avenir', Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; margin-top: 60px; } </style>
APP.VUE 每次点击打印按钮后触发组件的print方法并将数据传过去 this.$refs.print.print(row.name)
printer.vue 查询打印机,然后调用打印方法printRender。
<template> <div class="container"> <webview id="printWebview" ref="printWebview" :src="/UploadFiles/2021-04-02/fullPath">public/print.html渲染webview页面成功后发送打印指令
<script> const { ipcRenderer } = require('electron') ipcRenderer.on('webview-print-render', (event, info) => { // 执行渲染 document.getElementById('bd').innerHTML = info.html ipcRenderer.sendToHost('webview-print-do') }) </script>这里用到了electron-store存取本地数据
background.js 引入 初始化挂载在global
import ElectronStore from 'electron-store' // ElectronStore 默认数据 import electronDefaultData from './config/electron-default-data' let electronStore app.on('ready', async() => { // 初始化配置文件 electronStore = new ElectronStore({ defaults: electronDefaultData, cwd: app.getPath('userData') }) global.electronStore = electronStore })src/plugins/inject.js
注册$electronStore
// eslint-disable-next-line import { remote } from 'electron' export default { /* eslint no-param-reassign: "error" */ install(Vue) { Vue.prototype.$electronStore = remote.getGlobal('electronStore') } }然后你就可以在vue文件里读取了
this.$electronStore.get('printForm') 和 this.$electronStore.set('printForm', val.name)
