页面打印功能很常见，总结一下：
1、打印表格中的数据
页面引入jquery，也可以不引入，使用jquery操作DOM对象是很方便的
这是一个简单的演示：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<script src="js/jquery-3.3.1.min.js"></script>
</head>
<body>
<div id="dayin"><!--startprint-->
<table border="1" cellspacing="0" width="100%">
<caption>员工考核管理</caption>
<thead>
<tr>
<th>编号</th>
<th>姓名</th>
<th>年龄</th>
<th>地址</th>
<th>用户名</th>
<th>邮箱</th>
<th>手机号</th>
<th>电话号码</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>张三</td>
<td>22</td>
<td>上海址</td>
<td>asdf</td>
<td>[email protected]</td>
<td>123123123123123</td>
<td>11111111111</td>
</tr>
<tr>
<td>1</td>
<td>张三</td>
<td>22</td>
<td>上海址</td>
<td>asdf</td>
<td>[email protected]</td>
<td>123123123123123</td>
<td>11111111111</td>
</tr>
</tbody>
</table>
<!--endprint-->
</div>
<iframe id="iframe1" style="display: none"></iframe>
<button>打印</button>
</body>
<script type="text/javascript">
$("button").click(function(){
bdhtml=$("#dayin").html();
//alert(bdhtml);
sprnstr="<!--startprint-->"; //开始打印标识字符串有17个字符
eprnstr="<!--endprint-->"; //结束打印标识字符串
prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17); //从开始打印标识之后的内容
prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));//截取开始标识和结束标识之间的内容
var iframe = null;
iframe = document.getElementById("iframe1")
var iwindow = null;
var iwindow = iframe.contentWindow;//获取iframe的window对象
iwindow.document.close();
iwindow.document.write(prnhtml);
iwindow.print(); //调用浏览器的打印功能打印指定区域
});
</script>
</html>
这是打印表格数据的方法，很简单吧！主要是 "<!--startprint-->" 和 "<!--endprint-->"比较重要，直接影响打印的内容，所以位置请放正确！
2、打印页面
网上有一种jqprint插件，其实也是js打印，打印的是整个页面内容，如果需要打印表格数据，可以把需要打印的表格做成单独的页面来进行打印。
引入jquery，jquery不必多说，引入jquery.jqprint-0.3.js；
jquery.jqprint-0.3.js源码如下，不多，直接复制到页面中就行；
// -----------------------------------------------------------------------
// Eros Fratini - [email protected]
// jqprint 0.3
//
// - 19/06/2009 - some new implementations, added Opera support
// - 11/05/2009 - first sketch
//
// Printing plug-in for jQuery, evolution of jPrintArea: http://plugins.jquery.com/project/jPrintArea
// requires jQuery 1.3.x

(function($) {
var opt;
$.fn.jqprint = function (options) {
opt = $.extend({}, $.fn.jqprint.defaults, options);
var $element = (this instanceof jQuery) ? this : $(this);
if (opt.operaSupport && $.browser.opera)
{
var tab = window.open("","jqPrint-preview");
tab.document.open();
var doc = tab.document;
}
else
{
var $iframe = $("<iframe />");
if (!opt.debug) { $iframe.css({ position: "absolute", width: "0px", height: "0px", left: "-600px", top: "-600px" }); }
$iframe.appendTo("body");
var doc = $iframe[0].contentWindow.document;
}
if (opt.importCSS)
{
if ($("link[media=print]").length > 0)
{
$("link[media=print]").each( function() {
doc.write("<link type=‘text/css‘ rel=‘stylesheet‘ href=‘" + $(this).attr("href") + "‘ media=‘print‘ />");
});
}
else
{
$("link").each( function() {
doc.write("<link type=‘text/css‘ rel=‘stylesheet‘ href=‘" + $(this).attr("href") + "‘ />");
});
}
}
if (opt.printContainer) { doc.write($element.outer()); }
else { $element.each( function() { doc.write($(this).html()); }); }
doc.close();
(opt.operaSupport && $.browser.opera ? tab : $iframe[0].contentWindow).focus();
setTimeout( function() { (opt.operaSupport && $.browser.opera ? tab : $iframe[0].contentWindow).print(); if (tab) { tab.close(); } }, 1000);
}
$.fn.jqprint.defaults = {
debug: false,
importCSS: true,
printContainer: true,
operaSupport: true
};
// Thanks to 9__, found at http://users.livejournal.com/9__/380664.html
jQuery.fn.outer = function() {
return $($(‘<div></div>‘).html(this.clone())).html();
}
})(jQuery);
完整html页面：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>jQuery打印插件jqprint</title>
<script language="javascript" src="js/jquery-3.3.1.min.js"></script>
<script src="js/jquery-migrate-1.2.1.min.js"></script>
<script language="javascript" src="js/jquery.jqprint-0.3.js"></script>
<script language="javascript">
function a(){
$("#ddd").jqprint();
}
</script>
</head>
<body>
<div id="ddd">
<table width="100%" border="1" cellspacing="0">
<tr>
<td>test</td>
<td>test</td>
<td>test</td>
<td>test</td>
<td>test</td>
</tr>
<tr>
<td>test</td>

<td>test</td>
<td>test</td>
<td>test</td>
</tr>
</table>
</div>
<input type="button" onclick=" a()" value="打印"/>
<div style="text-align:center;margin:50px 0; font:normal 14px/24px ‘MicroSoft YaHei‘;">
</div>
</body>
</html>
在浏览器中打开，可能会出现这样的错误：

至此，问题应该是解决了，页面也可以正常打印。
3、强大的打印功能jatoolsPrinter
据说很强大，不过没有用过，网上可以找到一些教程可以学习。
