<div id="printArea">
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
<!-- Page break -->
<div class="pagebreak"> </div>
It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

我认为目前提出的解决方案有以下缺点:
CSS媒体查询解决方案假设只有一个div要打印。 javascript解决方案只适用于特定的浏览器。 破坏父窗口内容并重新创建会造成混乱。
我改进了上面的解决方案。下面是我测试过的一种方法，效果非常好，有以下好处。
适用于所有浏览器，包括IE, Chrome, Safari和firefox。 不会破坏和重载父窗口。 可以在页面上打印任意数量的DIV。 使用HTML模板避免容易出错的字符串连接。
注意事项:
必须在新创建的窗口上有一个onload="window.print()"。 不要从父类调用targetwindow.close()或targetwindow.print()。 确保执行targetwindow.document.close()和target.focus() 我使用的是jquery，但你也可以使用简单的javascript做同样的技术。 你可以在这里看到它的行动https://math.tools/table/multiplication。通过单击框头上的打印按钮，可以分别打印每个表。
<script id="print-header" type="text/x-jquery-tmpl"> <html> <header> <title>Printing Para {num}</title> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css"> <style> body { max-width: 300px; } </style> </header> <body onload="window.print()"> <h2>Printing Para {num} </h2> <h4>https://math.tools</h4> </script> <script id="print-footer" type="text/x-jquery-tmpl"> </body> </html> </script> <script> $('.printthis').click(function() { num = $(this).attr("data-id"); w = window.open(); w.document.write( $("#print-header").html().replace("{num}",num) + $("#para-" + num).html() + $("#print-footer").html() ); w.document.close(); w.focus(); //w.print(); Don't do this otherwise chrome won't work. Look at the onload on the body of the newly created window. ///w.close(); Don't do this otherwise chrome won't work }); </script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <a class="btn printthis" data-id="1" href="#" title="Print Para 1"><i class="fa fa-print"></i> Print Para 1</a> <a class="btn printthis" data-id="2" href="#" title="Print Para 2"><i class="fa fa-print"></i> Print Para 2</a> <p class="para" id="para-1"> Para 1 : Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

这是一个非常老的帖子，但这里是我的更新，我使用正确的答案。我的解决方案也使用jQuery。
这一点是使用正确的打印视图，包括所有样式表的正确格式，也要在大多数浏览器支持。
function PrintElem(elem, title, offset)
{
// Title constructor
title = title || $('title').text();
// Offset for the print
offset = offset || 0;
// Loading start
var dStart = Math.round(new Date().getTime()/1000),
$html = $('html');
i = 0;
// Start building HTML
var HTML = '<html';
if(typeof ($html.attr('lang')) !== 'undefined') {
HTML+=' lang=' + $html.attr('lang');
}
if(typeof ($html.attr('id')) !== 'undefined') {
HTML+=' id=' + $html.attr('id');
}
if(typeof ($html.attr('xmlns')) !== 'undefined') {
HTML+=' xmlns=' + $html.attr('xmlns');
}
// Close HTML and start build HEAD
HTML+='><head>';
// Get all meta tags
$('head > meta').each(function(){
var $this = $(this),
$meta = '<meta';
if(typeof ($this.attr('charset')) !== 'undefined') {
$meta+=' charset=' + $this.attr('charset');
}
if(typeof ($this.attr('name')) !== 'undefined') {
$meta+=' name=' + $this.attr('name');
}
if(typeof ($this.attr('http-equiv')) !== 'undefined') {
$meta+=' http-equiv=' + $this.attr('http-equiv');
}
if(typeof ($this.attr('content')) !== 'undefined') {
$meta+=' content=' + $this.attr('content');
}
$meta+=' />';
HTML+= $meta;
i++;
}).promise().done(function(){
// Insert title
HTML+= '<title>' + title + '</title>';
// Let's pickup all CSS files for the formatting
$('head > link[rel="stylesheet"]').each(function(){
HTML+= '<link rel="stylesheet" href="' + $(this).attr('href') + '" />';
i++;
}).promise().done(function(){
// Print setup
HTML+= '<style>body{display:none;}@media print{body{display:block;}}</style>';
// Finish HTML
HTML+= '</head><body>';
HTML+= '<h1 class="text-center mb-3">' + title + '</h1>';
HTML+= elem.html();
HTML+= '</body></html>';
// Open new window
var printWindow = window.open('', 'PRINT', 'height=' + $(window).height() + ',width=' + $(window).width());
// Append new window HTML
printWindow.document.write(HTML);
printWindow.document.close(); // necessary for IE >= 10
printWindow.focus(); // necessary for IE >= 10*/
console.log(printWindow.document);
/* Make sure that page is loaded correctly */
$(printWindow).on('load', function(){
setTimeout(function(){
// Open print
printWindow.print();
// Close on print
setTimeout(function(){
printWindow.close();
return true;
}, 3);
}, (Math.round(new Date().getTime()/1000) - dStart)+i+offset);
});
});
});
}
之后你只需要这样的东西:
$(document).on('click', '.some-print', function() {
PrintElem($(this), 'My Print Title');
return false;
});
试一试。
我编写了一个插件来解决这种情况。我对现有的插件不满意，开始做一些更广泛/可配置的东西。

我使用Bill Paetzke的答案打印一个div包含图像，但它不能与谷歌chrome
我只需要添加这一行myWindow.onload=function(){使它工作，这里是完整的代码
<html>
<head>
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.1.min.js"> </script>
<script type="text/javascript">
function PrintElem(elem) {
Popup($(elem).html());
}
function Popup(data) {
var myWindow = window.open('', 'my div', 'height=400,width=600');
myWindow.document.write('<html><head><title>my div</title>');
/*optional stylesheet*/ //myWindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />');
myWindow.document.write('</head><body >');
myWindow.document.write(data);
myWindow.document.write('</body></html>');
myWindow.document.close(); // necessary for IE >= 10
myWindow.onload=function(){ // necessary if the div contain images
myWindow.focus(); // necessary for IE >= 10
myWindow.print();
myWindow.close();
};
}
</script>
</head>
<body>
<div id="myDiv">
This will be printed.
<img src="image.jpg"/>
</div>
<div>
This will not be printed.
</div>
<div id="anotherDiv">
Nor will this.
</div>
<input type="button" value="Print Div" onclick="PrintElem('#myDiv')" />
</body>
</html>
如果有人只是需要打印一个带有id的div，他不需要加载jquery
这里是做这件事的纯javascript代码
<html>
<head>
<script type="text/javascript">
function PrintDiv(id) {
var data=document.getElementById(id).innerHTML;
var myWindow = window.open('', 'my div', 'height=400,width=600');
myWindow.document.write('<html><head><title>my div</title>');
/*optional stylesheet*/ //myWindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />');
myWindow.document.write('</head><body >');
myWindow.document.write(data);
myWindow.document.write('</body></html>');
myWindow.document.close(); // necessary for IE >= 10
myWindow.onload=function(){ // necessary if the div contain images
myWindow.focus(); // necessary for IE >= 10
myWindow.print();
myWindow.close();
};
}
</script>
</head>
<body>
<div id="myDiv">
This will be printed.
<img src="image.jpg"/>
</div>
<div>
This will not be printed.
</div>
<div id="anotherDiv">
Nor will this.
</div>
<input type="button" value="Print Div" onclick="PrintDiv('myDiv')" />
</body>
</html>
我希望这能帮助到一些人
