        if (ifr.readyState == 'complete') {
              ifr.contentWindow.focus();
              ifr.contentWindow.print();
           }
       }
 }

Answer 1

I suspect that's because the whole window gets printed (which has the current view of the iframe with the 1st page of the PDF rendered). 我怀疑这是因为整个窗口都被打印出来（其中包含iframe的当前视图以及PDF的第一页）。 Use <object> instead: 改为使用<object> ：

<!DOCTYPE html>
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge"/>

    <script>
    function PrintPdf() {
        idPrint.disabled = 0;
        idPdf.Print();
    }

    function idPdf_onreadystatechange() {
        if (idPdf.readyState === 4)
            setTimeout(PrintPdf, 1000);
    }
    </script>

</head>

<body>
    <button id="idPrint" disabled=1 onclick="PrintPdf()">Print</button>
    <br>
    <object id="idPdf" onreadystatechange="idPdf_onreadystatechange()"
        width="300" height="400" type="application/pdf"
        data="test.pdf?#view=Fit&scrollbar=0&toolbar=0&navpanes=0">
        <span>PDF plugin is not available.</span>
    </object>
</body>

This code is verified with IE. 此代码已通过IE验证。 Other browsers will still render the PDF, but may not print it. 其他浏览器仍将呈现PDF，但可能无法打印。

[UPDATE] If you need dynamic loading and printing, the changes to the above code are minimal: [更新]如果您需要动态加载和打印，对上述代码的更改是最小的：

<!DOCTYPE html>
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge"/>

    <script>
    function PrintPdf() {
        idPdf.Print();
    }

    function idPdf_onreadystatechange() {
        if (idPdf.readyState === 4)
            setTimeout(PrintPdf, 1000);
    }

    function LoadAndPrint(url)
    {
        idContainer.innerHTML = 
            '<object id="idPdf" onreadystatechange="idPdf_onreadystatechange()"'+
                'width="300" height="400" type="application/pdf"' +
                'data="' + url + '?#view=Fit&scrollbar=0&toolbar=0&navpanes=0">' +
                '<span>PDF plugin is not available.</span>'+
            '</object>';
    }
    </script>
</head>

<body>
    <button id="idPrint" onclick="LoadAndPrint('http://localhost/example.pdf')">Load and Print</button>
    <br>
    <div id="idContainer"></div>
</body>

Answer 2

<iframe src="teste.pdf" id="meupdf" width="800" height="600" />

function printPdf) {

    var PDF = document.getElementById("meupdf");
    PDF.focus();
    PDF.contentWindow.print();
}
