导出excel打印
private void ImageButton1_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
Response.Clear();
Response.Buffer= true;
Response.AppendHeader("Content-Disposition","attachment;filename=Borrow.xls");
Response.ContentEncoding=System.Text.Encoding.GetEncoding("gb2312");
Response.ContentType = "application/ms-excel";
this.EnableViewState = false;
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true);
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
Table3.RenderControl(oHtmlTextWriter);
Response.Charset="gb2312";
Response.Write(oStringWriter.ToString());
Response.End();
}
红色为导出文件名和要导出页面中的table
首先在网页中添加：
<OBJECT id="WebBrowser" height="0" width="0" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"
VIEWASTEXT>
</OBJECT>
然后就可以依次加入功能按钮了：
<input onclick="document.all.WebBrowser.ExecWB(6,1)" type="button" value="打印"> <input onclick="document.all.WebBrowser.ExecWB(6,6)" type="button" value="直接打印">
<input onclick="document.all.WebBrowser.ExecWB(8,1)" type="button" value="页面设置">
<input onclick="document.all.WebBrowser.ExecWB(7,1)" type="button" value="打印预览"> <INPUT type="button" value="关闭窗口" onclick="javascript:window.close()">
将这两块东西放到<center class=noprint></center>就不会打印这些按钮了。当然要定义noprint了：
<style media="print">.Noprint {}{ DISPLAY: none }</style>只要把不想打印的东西的css设置成noprint就可以了。
现在就实现了基本的web打印，需要注意的情况如下：
必须将ie的internet选项的安全设置中对于没有标记为安全的ActiveX控件进行设置成提示或者启用，否则会报错，导致不可用。
如果在vs.net编辑环境下编辑该页面，它经常自动的给object添加多余的参数，有了这些东西，打印就会出错，所以要记得最后保存的时候删除它们。
为了简便并且达到最好的效果，我们可以在一个页面实现编辑和打印，这时候会需要很多的textbox，我们把它的css设置成.edittext
{
overflow-y:visible;
width: 100%;
border-top: none;
border-right: none;
border-bottom: none;
border-left: none;
}就可以实现在打印的时候不显示边框和multiline的textbox不显示滚动条了。
还有一些小经验就是在设置标格宽度的时候，对于A4纸张，横打用920，竖打用640，效果最好。
1、控制"纵打"、 横打”和“页面的边距。
（1）<script defer>
function SetPrintSettings() {
// -- advanced features
factory.printing.SetMarginMeasure(2) // measure margins in inches
factory.SetPageRange(false, 1, 3) // need pages from 1 to 3
factory.printing.printer = "HP DeskJet 870C"
factory.printing.copies = 2
factory.printing.collate = true
factory.printing.paperSize = "A4"
factory.printing.paperSource = "Manual feed"
// -- basic features
factory.printing.header = "This is MeadCo"
factory.printing.footer = "Advanced Printing by scriptX"
factory.printing.portrait = false
factory.printing.leftMargin = 1.0
factory.printing.topMargin = 1.0
factory.printing.rightMargin = 1.0
factory.printing.bottomMargin = 1.0
}
</script>
（2）
<script language="javascript">
function printsetup(){
// 打印页面设置
wb.execwb(8,1);
}
function printpreview(){
// 打印页面预览
wb.execwb(7,1);
}
function printit()
{
if (confirm(''确定打印吗？'')) {
wb.execwb(6,6)
}
}
</script>
</head>
<body>
<OBJECT classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"
height=0 id=wb name=wb width=0></OBJECT>
<input type=button name=button_print value="打印"
onclick="javascript:printit()">
<input type=button name=button_setup value="打印页面设置"
onclick="javascript:printsetup();">
<input type=button name=button_show value="打印预览"
onclick="javascript:printpreview();">
<input type=button name=button_fh value="关闭"
onclick="javascript:window.close();">
------------------------------------------------
关于这个组件还有其他的用法，列举如下：
WebBrowser.ExecWB(1,1) 打开
Web.ExecWB(2,1) 关闭现在所有的IE窗口，并打开一个新窗口
Web.ExecWB(4,1) 保存网页
Web.ExecWB(6,1) 打印
Web.ExecWB(7,1) 打印预览
Web.ExecWB(8,1) 打印页面设置
Web.ExecWB(10,1) 查看页面属性
Web.ExecWB(15,1) 好像是撤销，有待确认
Web.ExecWB(17,1) 全选
Web.ExecWB(22,1) 刷新
Web.ExecWB(45,1) 关闭窗体无提示
2、分页打印
<HTML>
<HEAD>
<STYLE>
P {}{page-break-after: always}
</STYLE>
</HEAD>
<BODY>
<%while not rs.eof%>
<P><%=rs(0)%></P>
<%rs.movenext%>
<%wend%>
</BODY>
</HTML>
3、ASP页面打印时如何去掉页面底部的路径和顶端的页码编号
（1）ie的文件-〉页面设置-〉讲里面的页眉和页脚里面的东西都去掉，打印就不出来了。
（2）<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<META NAME="Generator" CONTENT="EditPlus">
<META NAME="Author" CONTENT="YC">
<script language="VBscript">
dim hkey_root,hkey_path,hkey_key
hkey_root="HKEY_CURRENT_USER"
hkey_path="\Software\Microsoft\Internet Explorer\PageSetup"
''//设置网页打印的页眉页脚为空
function pagesetup_null()
on error resume next
Set RegWsh = CreateObject("Wscript.Shell")
hkey_key="\header"
RegWsh.RegWrite hkey_root+hkey_path+hkey_key,""
hkey_key="\footer"
RegWsh.RegWrite hkey_root+hkey_path+hkey_key,""
end function
''//设置网页打印的页眉页脚为默认值
function pagesetup_default()
on error resume next
Set RegWsh = CreateObject("Wscript.Shell")
hkey_key="\header"
RegWsh.RegWrite hkey_root+hkey_path+hkey_key,"&w&b页码，&p/&P"
hkey_key="\footer"
RegWsh.RegWrite hkey_root+hkey_path+hkey_key,"&u&b&d"
end function
</script>
</HEAD>
<BODY>
<br/>
<br/>
<br/>
<br/>
<br/>
<br/><p align=center>
<input type="button" value="清空页码" onclick=pagesetup_null()> <input type="button" value="恢复页吗" onclick=pagesetup_default()><br/>
</p>
</BODY>
</HTML>
4、浮动帧打印
<script LANGUAGE=javascript>
function button1_onclick() {
var odoc=window.iframe1.document;
var r=odoc.body.createTextRange();
var stxt=r.htmlText;
alert(stxt)
var pwin=window.open("","print");
pwin.document.write(stxt);
pwin.print();
}
</script>
4、用FileSystem组件实现WEB应用中的本地特定打印
<script Language=VBscript>
function print_onclick //打印函数
dim label
label=document.printinfo.label.value //获得HTML页面的数据
set objfs=CreateObject("scripting.FileSystemObject") //创建FileSystem组件对象的实例
set objprinter=objfs.CreateTextFile ("LPT1:",true) //建立与打印机的连接
objprinter.Writeline("__________________________________") //输出打印的内容
objprinter.Writeline("| |")
objprinter.Writeline("| 您打印的数据是："&label& " |”)
objprinter.Writeline("| |")
objprinter.Writeline("|_________________________________|")
objprinter.close //断开与打印机的连接
set objprinter=nothing
set objfs=nothing // 关闭FileSystem组件对象
end function
</script>
服务器端脚本：
<%………
set conn=server.CreateObject ("adodb.connection")
conn.Open "DSN=name;UID=XXXX;PWD=XXXX;"
set rs=server.CreateObject("adodb.recordset")
rs.Open(“select ……”),conn,1,1
……….%> //与数据库进行交互
HTML页面编码：
<HTML>
………
<FORM ID=printinfo NAME="printinfo" >
<INPUT type="button" value="打印>>" id=print name=print > //调用打印函数
<INPUT type=hidden id=text1 name=label value=<%=………%>> //保存服务器端传来的数据
………
</HTML>
//打印分页
<p style="page-break-after:always">page1</p>
<p style="page-break-after:always">page2</p>
//设置打印
<br />
<object id="factory" style="display:none" viewastext <br />
classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814" <br />
codebase="http://www.meadroid.com/scriptx/ScriptX.cab#Version=5,60,0,360" <br />
></object> <br />
<input type=button value=页面设置 onclick="factory.printing.PageSetup()"> <br />
<input type=button value=打印预览 onclick="factory.printing.Preview()"> <br />
<br />
<script language=javascript> <br />
function window.onload() <br />
{ <br />
// -- advanced features <br />
factory.printing.SetMarginMeasure(2) // measure margins in inches <br />
factory.printing.SetPageRange(false, 1, 3) // need pages from 1 to 3 <br />
factory.printing.printer = "HP DeskJet 870C" <br />
factory.printing.copies = 2 <br />
factory.printing.collate = true <br />
factory.printing.paperSize = "A4" <br />
factory.printing.paperSource = "Manual feed" <br />
// -- basic features <br />
factory.printing.header = "居左显示&b居中显示&b居右显示页码，第&p页/共&P页" <br />
factory.printing.footer = "（自定义页脚）" <br />
factory.printing.portrait = false <br />
factory.printing.leftMargin = 0.75 <br />
factory.printing.topMargin = 1.5 <br />
factory.printing.rightMargin = 0.75 <br />
factory.printing.bottomMargin = 1.5 <br />
} <br />
function Print(frame) { <br />
factory.printing.Print(true, frame) // print with prompt <br />
} <br />
</script> <br />
<input type=button value="打印本页" onclick="factory.printing.Print(false)"> <br />
<input type=button value="页面设置" onclick="factory.printing.PageSetup()"> <br />
<input type=button value="打印预览" onclick="factory.printing.Preview()"><br> <br />
