实现

1、示例代码地址

https://igor-vladyka.github.io/leaflet.browser.print/examples/savePNG.html

访问并查看网页源码，下载并引入所需依赖


    <script type="text/javascript" src="https://unpkg.com/leaflet@1.7.1/dist/leaflet.js"></script>
    <script type="text/javascript" src="./js/leaflet.browser.print.js"></script>
    <script type="text/javascript" src="./js/dom-to-image.js"></script>

2、加载导出图片控件

        var saveAsImage = function () {
    return domtoimage.toPng(document.body)
      .then(function (dataUrl) {
       var link = document.createElement('a');
       link.download = map.printControl.options.documentTitle || "exportedMap" + '.png';
       link.href = dataUrl;
       link.click();
      });
   }
        //加载导出图片控件
        L.control.browserPrint({
            documentTitle: "printImage",
            printModes: [
                L.BrowserPrint.Mode.Landscape(),
            ],
            printFunction: saveAsImage
        }).addTo(map);
