Answer 2

    pd.PrinterSettings.PrinterName = "发送至 OneNote 2010"; 
这里不是写的打印机么？
如果不写这句就是用默认打印机，如果要选打印机，那你自己加一个PrintDialog

WebBrowser组件execWB方法进行打印示例
//打印页面设置
<form id="form1" runat="server">
    <div>
     <table>
                <tr>
                    <td style="width: 466px;  text-align: center;">
                        <asp:Label ID="Label1" runat="server" Font-Size="12pt" Font-Bold="True" ></asp:Label>
                      </td></tr>
                    <tr><td style="font-size: 9pt; width: 466px; text-indent: 8pt; text-align: left; height: 380px;">
                        <asp:Label ID="Label2" runat="server" Font-Size="9pt" Height="412px" 
                            Width="430px"  BorderWidth="1px" ForeColor="#404040"></asp:Label>
                      </td>
                </tr>
                <tr>
                    <td style="text-align: center; width: 466px; height: 46px;">
                <object id="WebBrowser" height="0" width="0" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2">
                </object>
                <asp:Panel ID="panel1" runat="server" Width="460px" Height="12px">
                <input onclick="document.all.WebBrowser.ExecWB(6,1);" type="button" value="打印" id="Button1" > 
                <input onclick="document.all.WebBrowser.ExecWB(6,6);" type="button" value="直接打印"  id="Button2">
                <input onclick="document.all.WebBrowser.ExecWB(8,1);" type="button" value="页面设置"  id="Button3">
                <input onclick="document.all.WebBrowser.ExecWB(7,1);" type="button" value="打印预览" id="Button4" >
                <input type="button" value="关闭窗口" onclick="javascript:window.close()"  id="Button5">
                        </asp:Panel></td>
                </tr>
            </table>
    </div>
</form>
//处理打印设置
public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string path = Server.MapPath("App_Data\\jytk.txt");
        System.IO.StreamReader reader = new System.IO.StreamReader(path, System.Text.Encoding.Default);
        this.Label1.Text = reader.ReadLine();
        this.Label2.Text = reader.ReadToEnd();
        reader.Close();
    }
}
