excl打印功能请教

[walin1]

在一个C#网站上的一个功能，服务器端中把信息导入到EXCL中后如何选择指定打印机打印该EXCL文档？

csdn上很多这种代码

    /// <summary>
    /// 导出到Excel事件
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void btnExcel_Click(object sender, EventArgs e)
    {
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename=WebMail" + DateTime.Now.ToString("yyyy-MM-dd") + ".xls");
        // 如果设置为 UTF7;导出的文件将会出现乱码！！！
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
        Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
        this.dlWebMailData.RenderControl(oHtmlTextWriter);
        Response.Output.Write(oStringWriter.ToString());
        Response.Flush();
        Response.End();
    }
