<script>
import { getLodop } from "../assets/LodopFuncs"; //导入模块
export default {
 name: "HelloWorld",
 data() {
  return {
   msg: "点击打印按钮",
  };
 },
 methods: {
  // btnClickPrint: function () {
  //  let LODOP = getLodop(); //调用getLodop获取LODOP对象
  //  LODOP.PRINT_INIT("");
  //  LODOP.ADD_PRINT_TEXT(50, 231, 260, 39, "打印内容");
  //  LODOP.PREVIEW();
  // },
  btnClickPrint() {
   let LODOP = getLodop(); //调用getLodop获取LODOP对象
   LODOP.PRINT_INIT("打印控件功能演示_Lodop功能_整页缩放打印输出");
   LODOP.ADD_PRINT_BARCODE(15, 15, 300, 300, "QRCode", "xxxxxxxxxxxxx");
   LODOP.SET_PRINT_STYLEA(0, "Stretch", 1); //(可变形)扩展缩放模式
   LODOP.PREVIEW(); //预览(预览打印无脚标)
   // LODOP.PRINT(); //打印
  },
 },
};
