        strokeWidth: 1 //单位 px
      })
        .then(base64url => {
          //自定义打印（设置纸张大小，打印标题）
          //     高       宽
          // A0：1189mm * 841mm
          // A1：841mm * 594mm
          // A2：594mm * 420mm
          // A3：420mm * 297mm
          // A4：297mm * 210mm
          //  页边距： 0.75 inch
          // A1: 23.39x33.11 inch
          // 打印机DPI：300DPI
          // 屏幕DPI  : 96DPI
          // width = (23.39 - 0.75 * 2) * 96  = 2101 px
          // height =  (33.11 - 0.75 * 2)* 96  = 3034 px
          // A4: 8.27x11.69 inch
          // 打印机DPI：300DPI
          // 屏幕DPI  : 96DPI
          // width = (8.27 - 0.75 * 2) * 96  = 650 px
          // height =  (11.69 - 0.75 * 2)* 96  = 978 px
          // 所以，当<table> 的width=650px, height=978px时，用IE 打印时，刚好能打印一页的A4纸．
          // //a1横向打印尺寸
          // var a1 = { width: "3034", height: "2101" };
          // //a4横向打印尺寸
          var a4 = { width: "978", height: "650" };
            let printOptions = {
              title: "打印标题(print title)",
              width: a4.width,
              height: a4.height,
              fontSize: "30",
              downLoadEnable: true //是否下载打印文件
            };
            CesiumPrint.print(base64url, printOptions);
          });
