javascript and printer
1. 直接调用 window.print();
2 . 可以只打印部分页面 (个人最喜欢)
页面内容 ：
<html>
...
<body>
<!-- some content -->
<!--startprint-->
print context
<!--endprint-->
<!-- some content -->
</body>
</html>
javascript代码 ：
<script type="text/javascript">
function printView(){
bdhtml=window.document.body.innerHTML;
sprnstr="<!--startprint-->"; // 这里要和页面标记完全统一
eprnstr="<!--endprint-->"; // 同上...
prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17);
prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));
window.document.body.innerHTML=prnhtml;
window.print();
window.document.body.innerHTML=bdhtml;
}
</script>
3. IEWebBrowser组件 :
<OBJECT classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2 height=0 id=WebBrowser width=0></OBJECT> 1. <input name=Button onClick=document.all.WebBrowser.ExecWB(1,1) type=button value=打开> 2. <input name=Button onClick=document.all.WebBrowser.ExecWB(2,1) type=button value=关闭所有> 3. <input name=Button onClick=document.all.WebBrowser.ExecWB(4,1) type=button value=另存为> 4. <input name=Button onClick=document.all.WebBrowser.ExecWB(6,1) type=button value=打印> 5. <input name=Button onClick=document.all.WebBrowser.ExecWB(6,6) type=button value=直接打印> 6. <input name=Button onClick=document.all.WebBrowser.ExecWB(7,1) type=button value=打印预览> 7. <input name=Button onClick=document.all.WebBrowser.ExecWB(8,1) type=button value=页面设置> 8. <input name=Button onClick=document.all.WebBrowser.ExecWB(10,1) type=button value=属性> 9. <input name=Button onClick=document.all.WebBrowser.ExecWB(17,1) type=button value=全选> 10. <input name=Button onClick=document.all.WebBrowser.ExecWB(22,1) type=button value=刷新> 11. <input name=Button onClick=document.all.WebBrowser.ExecWB(45,1) type=button value=关闭>
4. 使用ScriptX.cab控件
1．下载ScriptX.cab控件
官网http://www.meadroid.com/scriptx/index.asp
2．使用object元素，修改codebase，classid的值
这里调用控件ScriptX.cab
Java代码 复制代码
<OBJECT id="factory" style="DISPLAY: none" codeBase="${rootUrl}js/smsx.cab#VVersion=6,3,435,20" classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814" viewastext></OBJECT>
这段代码用来加载cab文件，clsid和codebase必须要和你下载的cab中的信息对应，否则组件会加载错误，这两项其实不难找，只要你用winrar打开你下载的cab文件，然后找到扩展名是.inf的文件，然后打开之，就能看到了。
3．调用控件脚本
Print.js文件
Java代码 复制代码
1. function setPrintBase(headerText,footerText,rootUrl) {
2.
3. // -- advanced features ，未曾使用过，有待确认。
4.
5. //factory.printing.SetMarginMeasure(2); // measure margins in inches
6.
7. //factory.SetPageRange(false, 1, 3);// need pages from 1 to 3
8.
9. //factory.printing.printer = "HP DeskJet 870C";
10.
11. //factory.printing.copies = 2;
12.
13. //factory.printing.collate = true;
14.
15. //factory.printing.paperSize = "A4";
16.
17. //factory.printing.paperSource = "Manual feed"
18.
19. var header = (headerText==null||headerText=="")?'默认页眉':headerText;
20.
21. var footer = (footerText==null||footerText=="")?'默认页角':footerText;
22.
23. factory.printing.header = "&b"+header+"&b" ;
24.
25. factory.printing.footer = "&b"+footer;
26.
27. factory.printing.portrait = true;
28.
29. factory.printing.leftMargin =10.00;
30.
31. factory.printing.topMargin =10.00;
32.
33. factory.printing.rightMargin =10.00;
34.
35. factory.printing.bottomMargin =10.00;
36.
37. }
测试代码 ：
<%@ page contentType="text/html;charset=GBK"%>
<html>
<head>
<meta http-equiv="imagetoolbar" content="no">
<script language="javascript" src="print.js"></script>
<style media="print">
.Noprint {DISPLAY: none;}
</style>
<title>打印测试</title>
</head>
<OBJECT id="factory" style="DISPLAY: none" codeBase="smsx.cab#VVersion=6,3,435,20" classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814" viewastext></OBJECT>
<script defer>
function window.onload() {
setPrintBase('页眉','页脚');
}
</script>
<body topmargin="0" leftmargin="0" rightmargin="0" bottommargin="0" marginwidth="0" marginheight="0">
<center class="Noprint">
<input type=button value="打印" onclick="factory.printing.Print(true)">
<input type=button value="页面设置" onclick="factory.printing.PageSetup()">
<input type=button value="打印预览" onclick="factory.printing.Preview()">
<input type="button" value="关闭" onclick="window.close();">
