1、首先利用一个类，ResponseHelper.cs,如下：

    using System;    using System.Collections.Generic;    using System.Linq;    using System.Web;    using System.Web.UI;    public class ResponseHelper    {        public static void Redirect(string url, string target, string windowFeatures)        {            HttpContext context = HttpContext.Current;            if ((String.IsNullOrEmpty(target) || target.Equals("_self", StringComparison.OrdinalIgnoreCase)) && String.IsNullOrEmpty(windowFeatures))            {                context.Response.Redirect(url);            }            else            {                Page page = (Page)context.Handler;                if (page == null)                {                    throw new InvalidOperationException("Cannot redirect to new window outside Page context.");                } url = page.ResolveClientUrl(url); string script; if (!String.IsNullOrEmpty(windowFeatures))                {                    script = @"<script>window.open(""{0}"", ""{1}"", ""{2}"");</script>";                }                else                {                    script = @"<script>window.open(""{0}"", ""{1}"");</script>";                }                script = String.Format(script, url, target, windowFeatures);                page.RegisterStartupScript("ddd", script);            }        }    }

2、在框架页中，进行页面跳转，代码：

ResponseHelper.Redirect("~/Vehicle/PrintTaskSheet.aspx?VID=" + braID, "_blank", "");

3、打印区代码：

<style media="print">        .Noprint        {            display: none;        }        /*用本样式在打印时隐藏非打印项目 */        .PageNext        {            page-break-after: always;        }        /*--控制分页*/    </style>

 <!--引入一个object-->    <object id="WebBrowser" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" height="0"        width="0">    </object>

               <div align="center">                    <span class="Noprint">                        <input name="button2" type="button" class="formbotton" onclick="document.all.WebBrowser.ExecWB(6,6)"                            value="直接打印" />                        <input name="button2" type="button" class="formbotton" onclick="document.all.WebBrowser.ExecWB(8,1)"                            value="页面设置" />                        <input name="button2" type="button" class="formbotton" onclick="document.all.WebBrowser.ExecWB(7,1)"                            value="打印预览" />                    </span>                </div>
