在所有流行的浏览器中使用Javascript打印PDF文件

Question

How to print a PDF file using Javascript across all popular browser? I have done quite extensive research on this question and there is no real solutions.

First approach is to use iFrame, however, iFrame is not a good practise. Code is listed as following.

function printIframePdf(){
    window.frames["printf"].focus();
    try {
        window.frames["printf"].print();
    }
    catch(e){
        window.print();
        console.log(e);
    }
}

Second approach is to use <embed> or <object> tag to display pdf and use document.getElementById(pdfID).print() to print. However, Chrome does not support this function. Code is listed as following.

function printObjectPdf() {
    document.getElementById('idPdf').Print();
}

Is there a good solution for this?
