  <script type="text/javascript">
    function printDiv() {
        var divToPrint = document.getElementById('printArea');  
    //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'\/\>");
    //HTML ELEMENTS THAT WE WANT TO HIDE FROM THE PRINTING AREA
        newWin.document.write("<style type='text/css'>@media print{.dataTables_info,.dataTables_filter{height:0!important;width:0!important;margin:0!important;padding:0!important;min-height:0!important;line-height:0!important;overflow:visible!important;visibility:hidden}");
    //General Styling for Printing

    //Some forced styling in css rules includying page break for a div
        newWin.document.write("body h1{font-size:1em; font-family:Verdana;} a.marked{color:black; text-decoration:none} .pagebreak { page-break-before: always; } ");

<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">&nbsp;</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。

这是我的jquery打印插件

(function ($) {

$.fn.printme = function () {
    return this.each(function () {
        var container = $(this);

        var hidden_IFrame = $('<iframe></iframe>').attr({
            width: '1px',
            height: '1px',
            display: 'none'
        }).appendTo(container);

        var myIframe = hidden_IFrame.get(0);

        var script_tag = myIframe.contentWindow.document.createElement("script");
        script_tag.type = "text/javascript";
        script = myIframe.contentWindow.document.createTextNode('function Print(){ window.print(); }');
        script_tag.appendChild(script);

        myIframe.contentWindow.document.body.innerHTML = container.html();
        myIframe.contentWindow.document.body.appendChild(script_tag);

        myIframe.contentWindow.Print();
        hidden_IFrame.remove();

    });
};
})(jQuery);

我认为有更好的解决办法。让你的div打印覆盖整个文档，但只在打印时:

@media print {
    .myDivToPrint {
        background-color: white;
        height: 100%;
        width: 100%;
        position: fixed;
        top: 0;
        left: 0;
        margin: 0;
        padding: 15px;
        font-size: 14px;
        line-height: 18px;
    }
}

我修改了@BillPaetski答案使用querySelector，添加可选的CSS，删除强制H1标签，并使标题可选地指定或从窗口拉出。它也不再自动打印，并公开内部内容，以便它们可以在包装器函数中切换或随你喜欢。

仅有的两个私有变量是tmpWindow和tmpDoc，尽管我相信标题，css和elem访问可能会有所不同，但应该假设所有函数参数都是私有的。

Code:

function PrintElem(elem, title, css) {
    var tmpWindow = window.open('', 'PRINT', 'height=400,width=600');
    var tmpDoc = tmpWindow.document;

    title = title || document.title;
    css = css || "";

    this.setTitle = function(newTitle) {
        title = newTitle || document.title;
    };

    this.setCSS = function(newCSS) {
        css = newCSS || "";
    };

    this.basicHtml5 = function(innerHTML) {
        return '<!doctype html><html>'+(innerHTML || "")+'</html>';
    };

    this.htmlHead = function(innerHTML) {
        return '<head>'+(innerHTML || "")+'</head>';
    };

    this.htmlTitle = function(title) {
        return '<title>'+(title || "")+'</title>';
    };

    this.styleTag = function(innerHTML) {
        return '<style>'+(innerHTML || "")+'</style>';
    };

    this.htmlBody = function(innerHTML) {
        return '<body>'+(innerHTML || "")+'</body>';
    };

    this.build = function() {
        tmpDoc.write(
            this.basicHtml5(
                this.htmlHead(
                    this.htmlTitle(title) + this.styleTag(css)
                ) + this.htmlBody(
                    document.querySelector(elem).innerHTML
                )
            )
        );
        tmpDoc.close(); // necessary for IE >= 10
    };

    this.print = function() {
        tmpWindow.focus(); // necessary for IE >= 10*/
        tmpWindow.print();
        tmpWindow.close();
    };

    this.build();
    return this;
}

Usage:

DOMPrinter = PrintElem('#app-container');
DOMPrinter.print();

下面是一个适用于IE和Chrome的IFrame解决方案:

function printHTML(htmlString) {
    var newIframe = document.createElement('iframe');
    newIframe.width = '1px';
    newIframe.height = '1px';
    newIframe.src = 'about:blank';

    // for IE wait for the IFrame to load so we can access contentWindow.document.body
    newIframe.onload = function() {
        var script_tag = newIframe.contentWindow.document.createElement("script");
        script_tag.type = "text/javascript";
        var script = newIframe.contentWindow.document.createTextNode('function Print(){ window.focus(); window.print(); }');
        script_tag.appendChild(script);

        newIframe.contentWindow.document.body.innerHTML = htmlString;
        newIframe.contentWindow.document.body.appendChild(script_tag);

        // for chrome, a timeout for loading large amounts of content
        setTimeout(function() {
            newIframe.contentWindow.Print();
            newIframe.contentWindow.document.body.removeChild(script_tag);
            newIframe.parentElement.removeChild(newIframe);
        }, 200);
    };
    document.body.appendChild(newIframe);
}
