打印DIV内容的最佳方法是什么?
当前回答
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。

与早期版本相比略有变化-在CHROME上测试
function PrintElem(elem)
{
var mywindow = window.open('', 'PRINT', 'height=400,width=600');
mywindow.document.write('<html><head><title>' + document.title + '</title>');
mywindow.document.write('</head><body >');
mywindow.document.write('<h1>' + document.title + '</h1>');
mywindow.document.write(document.getElementById(elem).innerHTML);
mywindow.document.write('</body></html>');
mywindow.document.close(); // necessary for IE >= 10
mywindow.focus(); // necessary for IE >= 10*/
mywindow.print();
mywindow.close();
return true;
}

//Firefox was just opening a new window with same content as opener and not performing the printing dialog, so needed to make it open a new instance of the window opener
newWin= window.open(self.location.href);
//We want to format the document appropriately
newWin.document.write("\<!DOCTYPE html\>\<html lang='es'\>\<head\>\<meta charset='utf-8'\/\>\<meta name='viewport' content='width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no'><meta http-equiv='X-UA-Compatible' content='IE=edge,chrome=1'\>\<meta name='HandheldFriendly' content='true'\/\>");

<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).

虽然@BC的答案最好打印一页。
但要打印多页A4大小的同时按ctrl+P以下解决方案可能会有所帮助。
@media print{
html *{
height:0px!important;
width:0px !important;
margin: 0px !important;
padding: 0px !important;
min-height: 0px !important;
line-height: 0px !important;
overflow: visible !important;
visibility: hidden ;
}
/*assing myPagesClass to every div you want to print on single separate A4 page*/
body .myPagesClass {
z-index: 100 !important;
visibility: visible !important;
position: relative !important;
display: block !important;
background-color: lightgray !important;
height: 297mm !important;
width: 211mm !important;
position: relative !important;
padding: 0px;
top: 0 !important;
left: 0 !important;
margin: 0 !important;
orphans: 0!important;
widows: 0!important;
overflow: visible !important;
page-break-after: always;
}
@page{
size: A4;
margin: 0mm ;
orphans: 0!important;
widows: 0!important;
}}

注意:这只适用于启用jQuery的站点
这个很酷的技巧非常简单。它在谷歌Chrome浏览器中为我工作。火狐不允许你在没有插件的情况下打印PDF文件。
首先，使用(Ctrl + Shift + I) / (Cmd + Option + I)打开检查器。 在控制台中输入以下代码:
var jqchild = document.createElement('script');
jqchild.src = "https://cdnjs.cloudflare.com/ajax/libs/jQuery.print/1.5.1/jQuery.print.min.js";
document.getElementsByTagName('body')[0].appendChild(jqchild);
$("#myDivWithStyles").print(); // Replace ID with yours
它启动打印对话框。打印出来或者保存成PDF格式(chrome)。完成了!
逻辑很简单。我们正在创建一个新的脚本标记，并将其附加在关闭主体标记的前面。我们在HTML中注入了一个jQuery打印扩展。用你自己的Div标签ID更改myDivWithStyles。现在它负责准备一个可打印的虚拟窗口。
在任何网站上尝试一下。唯一需要注意的是，有时巧妙地编写CSS会导致丢失样式。但大多数时候我们得到的是内容。
