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);

function printDomElement(element) {
    element.classList.add("printCss");

    let printId = "printId";
    let name = ".printCss";
    let rules = "-webkit-print-color-adjust:exact;height:100%;width:100%;position:fixed;top:0;left:0;margin:0;";

    var style = document.createElement('style');
    style.id = printId;
    style.media = "print";
    document.getElementsByTagName('head')[0].appendChild(style);

    if (!(style.sheet || {}).insertRule)(style.styleSheet || style.sheet).addRule(name, rules);
    else style.sheet.insertRule(name + "{" + rules + "}", 0);

    window.print();

    setTimeout(() => {
      element.classList.remove("printCss");
      let elem = document.getElementById(printId);
      if (elem) elem.remove();
    }, 500);

  }

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;
}}

$.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);

只需使用PrintJS

let printjs = document.createElement("script");
printjs.src = "https://printjs-4de6.kxcdn.com/print.min.js";
document.body.appendChild(printjs);

printjs.onload = function (){
    printJS('id_of_div_you_want_to_print', 'html');
}

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。

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;
}

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