Create a PDF file from HTML content

BlueForest85 Member Posts: 129 Green Ribbon

Hello everyone,

I'm wondering how I could generate a PDF file from HTML content.

I don't know if it's natively possible, but I took a peek on the plug-in page :

This one seems interesting, with its demo :

However I want to know your point of view about this and how to proceed.

Thank you for your experience !

    I use Chrome in headless mode as a Perl-based CGI web service.

    You call it with a URL as parameter and Perl runs Chrome's print-to-pdf feature on that URL passed.

    Basic Perl CGI script below. I wrote back in 2019. There were Chrome bugs with ignoring certs. And I do not know Perl.

    For APEX URLs you need to work around authentication and APEX item values for the page. I passed a "proxy URL" to the Perl CGI with a unique token parameter for the public APEX proxy page URL. This token was used to perform a transparent logon and redirect to the APEX page (with values), for Chrome to render (in headless mode) and save to PDF.

    # bug filed for https acceptInsecureCerts
    use CGI;
    $myCgi = new CGI;
    $base		= $myCgi->param('base');
    $pdfFile	= $myCgi->param('filename');
    $download	= $myCgi->param('auto-download');
    if (($base eq "") || ($base eq "null")) {
    	print "Expires: 0\n";
    	print "Pragma: no-cache\n";
    	print "Content-Type: text/plain;\n\n";
    	print "Parameter 'base' is required, but not detected.\nYour URL call cannot be serviced.\n";
    	print "\n\n";
    	print "usage:	base=<url>[&filename=<file.pdf>][&auto-download=yes]\n";
    $direct	= "/tmp/";
    $myFile	= "$direct".time()."_$$-1.pdf";
    # `google-chrome runs as --headless --disable-gpu --use-gl --virtual-time-budget=10000 --ignore-certificate-errors --print-to-pdf="$myFile" "$URL" 1>/dev/null 2>/dev/null`;
    # Have to run as chrome user in order for /home/chrome/.config to be used, containing wallet and certificates - thus sudo as chrome is used
    `sudo -u chrome /home/chrome/bin/google-chrome "$myFile" "$URL" `;
    print "X-cgi-name: PageToPDF.cgi - $$\n";
    print "X-pdf-url: $URL\n";
    print "Expires: 0\n";
    print "Pragma: no-cache\n";
    if ($pdfFile ne "") {
    	if ($download ne "") {
    		print "Content-Disposition: attachment; filename=\"$pdfFile\"\n";
    	else {
    		print "Content-Disposition: filename=\"$pdfFile\"\n";
    print "Content-Type: application/pdf;\n\n";
    open (FH, $myFile);
    while (my $line = <FH>) {
    	print ("$line");
    unlink( $myFile );

    I've used jsPDF for this. It lets you create a pdf of the whole page, or just a specific region if needed. After attaching the JavaScript libraries jsPDF and html2canvas, you can use this as a starting point (e.g. using a Print button):

    window.jsPDF = window.jspdf.jsPDF;
    var doc = new jsPDF();   
    doc.html(document.getElementById('container'), {
       callback: function (doc) {;
        width: 170,
        margin: [20, 0, 0, 20]

    where 'container' is the static ID of the region you want to save as a pdf.

    Saving the whole page as a pdf is easy, because you can use the native browser print option.
