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):==
