1.将LodopFuncs.js复制到项目中

var CreatedOKLodop7766=null;

//====判断是否需要安装CLodop云打印服务器:====

    } else

      };
    };
    return false;
  } catch(err) {return true;};
};

//====页面引用CLodop云打印必须的JS文件：====

  var head = document.head || document.getElementsByTagName("head")[0] || document.documentElement;
  var oscript = document.createElement("script");
  oscript.src ="http://localhost:8000/CLodopfuncs.js?priority=1";

2. 打印页面引入LodopFuncs.js

<script>

import { getLodop } from '@/assets/js/LodopFuncs'

</script>

3. 实现打印

页面：

<button
            v-if="ordersInfo.orderStatus == 1 || ordersInfo.orderStatus == 0"
            type="button"
            class="white green_bg dayin"
            @click="print1()"
          >
            打印
          </button>

js:

 print1(){
      if (this.arr.length > 0) { // arr为循环的数据 替换成自己的
        var LODOP = getLodop()
        // var totalPrint = 0 // 第几个
        // // 如果有预设的打印机名称，则设置，否则使用本机默认打印机
        // if (!this.isEmpty(this.print_info[0].打印机名称)) {
          
        // }
        LODOP.SET_PRINT_MODE('WINDOW_DEFPRINTER', "Xprinter-365b")
        // 循环打印
        for (var i = 0; i < this.arr.length; i++) {
          console.log(this.arr[i])
          // totalPrint++
  
            LODOP.SET_PRINT_PAGESIZE(1, 390, 300, '40mm') // 设定纸张大小:纵向，宽为0，高为0，纸张类型为148.5mm，
            LODOP.ADD_PRINT_TEXT(5, 0, 248, 30, this.ordersInfo.shopName) // 此为显示内容
            LODOP.SET_PRINT_STYLEA(0, 'FontSize', 8)
            //LODOP.ADD_PRINT_TEXT(5, 0, 157, 25, '小程序')

            //LODOP.ADD_PRINT_TEXT(5, 50, 228, 35, '自提') // 增加纯文本项:距离顶部31mm,距离左边312，宽度228，高度35

            LODOP.ADD_PRINT_TEXT(20, 0, 657, 25, "取餐号："+this.ordersInfo.pickupCode)
            LODOP.SET_PRINT_STYLEA(0, 'FontSize', 10)
            LODOP.ADD_PRINT_TEXT(36, 0, 646, 189, this.arr[i].name)
            LODOP.SET_PRINT_STYLEA(0, 'FontSize', 8)
            LODOP.ADD_PRINT_TEXT(52, 0, 346, 30, this.arr[i].specifications.indexOf("杯") > -1
                  ? "（" + this.arr[i].specifications.substring(0, 2) + "）"
                  : "")
            LODOP.SET_PRINT_STYLEA(0, 'FontSize', 8)
            LODOP.ADD_PRINT_TEXT(52, 0, 248, 30, this.arr[i].specifications.indexOf("杯") > -1
                  ? this.arr[i].specifications.substring(3)
                  : this.arr[i].specifications)
            LODOP.SET_PRINT_STYLEA(0, 'FontSize', 8)
            LODOP.ADD_PRINT_TEXT(67, 0, 248, 30, this.ordersInfo.updateTime
                ? this.ordersInfo.updateTime.substring(5, 10)
                : "")
            LODOP.SET_PRINT_STYLEA(0, 'FontSize', 8)
            LODOP.ADD_PRINT_TEXT(67, 30, 248, 30, this.ordersInfo.updateTime
                ? this.ordersInfo.updateTime.substring(10, 19)
                : "")
            LODOP.SET_PRINT_STYLEA(0, 'FontSize', 8)
            
            // LODOP.ADD_PRINT_TEXT(79, 0, 248, 30, this.ordersInfo.shopName)
            // LODOP.SET_PRINT_STYLEA(0, 'FontSize', 10)
            LODOP.ADD_PRINT_TEXT(82, 0, 248, 30, this.ordersInfo.notes ? "备注："+this.ordersInfo.notes : '')
            LODOP.SET_PRINT_STYLEA(0, 'FontSize', 8)
            // if (totalPrint == this.arr.length) { 
              // console.log(this.arr[i].name)
              LODOP.PRINT()
              // LODOP.PREVIEW() // 为防止真正打印，采用预览模式,预览模式只能预览一页，无法翻页，切会弹出‘有窗口已打开，先关闭它’提示
            
          // } 
        }
      }
    },
