打印时多余的空白页

标签： c# javascript jquery asp.net

我有一张要在网络表单上打印的图片。图像控件在运行时动态加载图像。页面上有一个打印按钮，可以打印到pdf选项。创建的pdf会生成一个额外的页面以及要打印的图像

px中图像的大小为649 * 602。

用于打印的javascript代码如下

 function printDiv(divName) {
            var title = document.title;
            document.title = '';
            var printContents = document.getElementById(divName).innerHTML;

            var originalContents = document.body.innerHTML;

            document.body.innerHTML = printContents;
            window.print();

            document.body.innerHTML = originalContents;
            document.title = title;
            return false;
        }

aspx页面包含以下内容

<body style="background: none; padding-top: 8%; padding-left: 2%;">
    <form id="form1" runat="server">
    <div style="float: left; padding: 1%; width: 55%;" id="divInstructions">
        <asp:Image ID="imgInstructionSheet" runat="server" />
    </div>
    <div style="padding-left: 3%; float: left;">
        <asp:ImageButton runat="server" ID="imgBtnPrint" SkinID="Print" OnClientClick="return printDiv('divInstructions')"
            ToolTip="Print" />

            <%-- <asp:ImageButton runat="server" ID="imgBtnPrint" SkinID="Print" OnClientClick="return window.print();"
            ToolTip="Print" />--%>
    </div>
    <div class="wrapper" style="float: left; width: 36%; padding-top: 1%;">
        <a href="#" class="instrulink" style="padding-left: 2%" onmouseover="DisplayInstruction();" onmouseout="RemoveInstruction();">Display Instructions</a>
        <div style="display: none; padding-top: 8%; margin-left: -8%; float: left; overflow: hidden;"
            id="printinstruction">
            <table style="background-color: lightgray; padding: 5px; -moz-border-radius: 5px;
                -webkit-border-radius: 5px; -khtml-border-radius: 5px; border-radius: 5px;">
                <tr>
                    <td>
                        <img src="../Images/PageSetUp.jpg" />
                    </td>
                </tr>
                <tr>
                    <td>
                        <ul>
                            <b style="font-family:Verdana;font-size:14px;"><u>For Proper Printout Follow The Instructions:</u></b>
                            <br />
                            <li class="cssLi">Click on File Menu Goto Page Setup.</li>
                            <li class="cssLi">In Page Setup Dialog Box.</li>
                            <li class="cssLi">Set Paper Size To Letter (8.5x11").</li>
                            <li class="cssLi">Set Left Margin as 0.5 and Right Margin as 0.5.</li>
                        </ul>
                    </td>
                </tr>
            </table>
        </div>
    </div>
    </form>
</body>

有什么方法可以消除多余的空白页面？ 我尝试缩小图像尺寸但没有效果。
