前言

此控件直接进行打印底部会有水印,通过官网购买可以解决;
如不想购买,可先执行预览,弹出预览框进行打印;
需要用到的js文件和api文档附后,请注意查看。
首先需要在局部或全局引入LodopFuncs.js文件
import {getLodop} from '../../../components/js/LodopFuncs'

方法中调用

print(){
   let LODOP = getLodop();
   LODOP.PRINT_INITA(0,0,800,1600,"打印库位名称");
   LODOP.SET_PRINT_PAGESIZE(1,700,500,"") //设定纸张大小
    LODOP.NewPage();//初始化
    LODOP.SET_PRINT_MODE("RESELECT_PRINTER",true);
    LODOP.ADD_PRINT_TEXT('10mm','50mm','30mm','20mm','iphone20Plus');//打印文字
    LODOP.SET_PRINT_STYLEA(0,"FontSize",30);//字体样式
    LODOP.ADD_PRINT_LINE('10mm','35mm','40mm','35mm',0,1);//打印直线
    LODOP.ADD_PRINT_BARCODE('10mm','2.5mm','35mm','35mm',"QRCode",'123456');//打印二维码
    LODOP.SET_PRINT_STYLEA(0,"AlignJustify",2);//二维码样式和规则
    LODOP.SET_PRINTER_INDEXA("TSC TTP-244 Pro");//选择打印机
   // LODOP.PRINT_DESIGN()//打开设置
   // LODOP.PREVIEW(); //预览
    LODOP.PRINT() //直接打印
  },

LodopFuncs.js文件

//==本JS是加载Lodop插件及CLodop服务的综合示例,可直接使用,建议看懂后融进自己页面程序==

var CreatedOKLodopObject, CLodopIsLocal, CLodopJsState;


//==判断是否需要CLodop(那些不支持插件的浏览器):==
export function needCLodop() {
  try {
    var ua = navigator.userAgent;
    if (ua.match(/Windows\sPhone/i))
      return true;
    if (ua.match(/iPhone|iPod|iPad/i))
      return true;
    if (ua.match(/Android/i))
      return true;
    if (ua.match(/Edge\D"head")[0] || document.documentElement;
  
  var JS1 = document.createElement("script");
  JS1.src = "http://localhost:8000/CLodopfuncs.js";
  head.insertBefore(JS1, head.firstChild);

  var JS2 = document.createElement("script");
  JS2.src = "http://localhost:18000/CLodopfuncs.js";
  head.insertBefore(JS2, head.firstChild);

  CLodopIsLocal = !!((JS1.src + JS2.src).match(/\/\/localho|\/\/127.0.0./i));

  if (JS1.attachEvent) {
  	CLodopJsState = "loading";
    var onChange = function(){ 
	   if (window.event.srcElement.readyState == 'loaded')        
	   CLodopJsState = "complete";
	};
	JS1.attachEvent('onreadystatechange',onChange);

}
