//打印可以使用lodop这个经典的前端打印控件
1、在vue assets目录新建LodopFuncs.js,(可以自由选择其他路径),里面的内容为：
var CreatedOKLodop7766=null;
//====判断是否需要安装CLodop云打印服务器:====
export function needCLodop(){
try{
var ua=navigator.userAgent;
if (ua.match(/WindowssPhone/i) !=null) return true;
if (ua.match(/iPhone|iPod/i) != null) return true;
if (ua.match(/Android/i) != null) return true;
if (ua.match(/EdgeD?d+/i) != null) return true;
var verTrident=ua.match(/TridentD?d+/i);
var verIE=ua.match(/MSIED?d+/i);
var verOPR=ua.match(/OPRD?d+/i);
var verFF=ua.match(/FirefoxD?d+/i);
var x64=ua.match(/x64/i);
if ((verTrident==null)&&(verIE==null)&&(x64!==null))
return true; else
if ( verFF !== null) {
verFF = verFF[0].match(/d+/);
if ((verFF[0]>= 42)||(x64!==null)) return true;
} else
if ( verOPR !== null) {
verOPR = verOPR[0].match(/d+/);
if ( verOPR[0] >= 32 ) return true;
} else
if ((verTrident==null)&&(verIE==null)) {
var verChrome=ua.match(/ChromeD?d+/i);
if ( verChrome !== null ) {
verChrome = verChrome[0].match(/d+/);
if (verChrome[0]>=42) return true;
};
};
return false;
} catch(err) {return true;};
};
//====页面引用CLodop云打印必须的JS文件：====
if (needCLodop()) {
var head = document.head || document.getElementsByTagName("head")[0] || document.documentElement;
var oscript = document.createElement("script");
oscript.src ="http://localhost:8000/CLodopfuncs.js?priority=1";
head.insertBefore( oscript,head.firstChild );
//引用双端口(8000和18000）避免其中某个被占用：
oscript = document.createElement("script");
oscript.src ="http://localhost:18000/CLodopfuncs.js?priority=0";
head.insertBefore( oscript,head.firstChild );
};
//====获取LODOP对象的主过程：====
export function getLodop(oOBJECT,oEMBED){
var strHtmInstall="<br><font color='#FF00FF'>打印控件未安装!点击这里<a href='install_lodop32.exe' target='_self'>执行安装</a>,安装后请刷新页面或重新进入。</font>";

var LODOP;
try{
var isIE = (navigator.userAgent.indexOf('MSIE')>=0) || (navigator.userAgent.indexOf('Trident')>=0);
if (needCLodop()) {
try{ LODOP=getCLodop();} catch(err) {};
if (!LODOP && document.readyState!=="complete") {alert("C-Lodop没准备好，请稍后再试！"); return;};

return LODOP;
} catch(err) {alert("getLodop出错:"+err);};
};
2、在util目录下，新建print.js,引用并封装刚才建的loadopFuncs.js文件
import { getLodop } from "@/assets/LodopFuncs";
export const printPdf = (html) => {
let LODOP = getLodop();
LODOP.SET_PRINT_STYLEA(0, "HtmWaitMilSecs", 1000);
LODOP.PRINT_INIT("订货单");
LODOP.SET_PRINT_STYLE("FontSize", 18);
LODOP.SET_PRINT_STYLE("Bold", 1);
LODOP.ADD_PRINT_HTM(
"0",
"0",
"100%",
"100%",
html
);
LODOP.PRINT();
}
3、页面引用并使用
import { printPdf } from "@/utils/print";
printpdf(html); //html指的是后台传过来的html面单信息.
//注意，需要到lodop官网，下载对应的
