JavaScript 網頁打印處理
1、控制"纵打"、 横打”和“页面的边距。
（1）<script defer>
function SetPrintSettings() {
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"
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="＆#106avascript">
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 ＆#118alue="打印"
＆#111nclick="＆#106avascript:printit()">
<input type=button name=button_setup ＆#118alue="打印页面设置"
#111nclick="＆#106avascript:printsetup();">
<input type=button name=button_show ＆#118alue="打印预览"
＆#111nclick="＆#106avascript:printpreview();">
<input type=button name=button_fh ＆#118alue="关闭"
＆#111nclick="＆#106avascript:window.close();">
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" ＆#118alue="清空页码" ＆#111nclick=pagesetup_null()> <input type="button" ＆#118alue="恢复页吗" ＆#111nclick=pagesetup_default()><br/>
</p>
</BODY>
</HTML>
4、浮动帧打印
<SCRIPT LANGUAGE=＆#106avascript>
function button1_＆#111nclick() {
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_＆#111nclick //打印函数
dim label
label=document.printinfo.label.＆#118alue //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" ＆#118alue="打印>>" id=print name=print > //调用打印函数
<INPUT type=hidden id=text1 name=label ＆#118alue=<%=………%>> //保存服务器端传来的数据
………
</HTML>
