//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(/Windows\sPhone/i) !=null) return true;
  if (ua.match(/iPhone|iPod/i) != null) return true;
  if (ua.match(/Android/i) != null) return true;
  if (ua.match(/Edge\D?\d+/i) != null) return true;
 
  var verTrident=ua.match(/Trident\D?\d+/i);
  var verIE=ua.match(/MSIE\D?\d+/i);
  var verOPR=ua.match(/OPR\D?\d+/i);
  var verFF=ua.match(/Firefox\D?\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(/Chrome\D?\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="
打印控件未安装!点击这里执行安装,安装后请刷新页面或重新进入。"; var strHtmUpdate="
打印控件需要升级!点击这里执行升级,升级后请重新进入。"; var strHtm64_Install="
打印控件未安装!点击这里执行安装,安装后请刷新页面或重新进入。"; var strHtm64_Update="
打印控件需要升级!点击这里执行升级,升级后请重新进入。"; var strHtmFireFox="

(注意:如曾安装过Lodop旧版附件npActiveXPLugin,请在【工具】->【附加组件】->【扩展】中先卸它)"; var strHtmChrome="

(如果此前正常,仅因浏览器升级或重安装而出问题,需重新执行以上安装)"; var strCLodopInstall="
CLodop云打印服务(localhost本地)未安装启动!点击这里执行安装,安装后请刷新页面。"; var strCLodopUpdate="
CLodop云打印服务需升级!点击这里执行升级,升级后请刷新页面。"; 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;}; if (!LODOP) { // if (isIE) document.write(strCLodopInstall); else // document.documentElement.innerHTML=strCLodopInstall+document.documentElement.innerHTML; // return; } else { if (CLODOP.CVERSION=0); //=====如果页面有Lodop就直接使用,没有则新建:========== if (oOBJECT!=undefined || oEMBED!=undefined) { if (isIE) LODOP=oOBJECT; else LODOP=oEMBED; } else if (CreatedOKLodop7766==null){ LODOP=document.createElement("object"); LODOP.setAttribute("width",0); LODOP.setAttribute("height",0); LODOP.setAttribute("style","position:absolute;left:0px;top:-100px;width:0px;height:0px;"); if (isIE) LODOP.setAttribute("classid","clsid:2105C259-1E0C-4534-8141-A753534CB4CA"); else LODOP.setAttribute("type","application/x-print-lodop"); document.documentElement.appendChild(LODOP); CreatedOKLodop7766=LODOP; } else LODOP=CreatedOKLodop7766; //=====Lodop插件未安装时提示下载地址:========== if ((LODOP==null)||(typeof(LODOP.VERSION)=="undefined")) { if (navigator.userAgent.indexOf(‘Chrome‘)>=0) document.documentElement.innerHTML=strHtmChrome+document.documentElement.innerHTML; if (navigator.userAgent.indexOf(‘Firefox‘)>=0) document.documentElement.innerHTML=strHtmFireFox+document.documentElement.innerHTML; if (is64IE) document.write(strHtm64_Install); else if (isIE) document.write(strHtmInstall); else document.documentElement.innerHTML=strHtmInstall+document.documentElement.innerHTML; return LODOP; }; }; if (LODOP.VERSION

  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

Lodop综合版(Lodop6.226+CLodop4.088),安装里面的install_lodop64.exe、CLodop_Setup_for_Win32NT.exe这两个文件
