print preview does not show any data in jQuery data table

Question

I'm working on implementing Copy, Excel, PDF, and Print. The first three are working with no issues, but Print is giving me problems. When trying to print, if I click the Print button, then opens the print preview page but no data show on the print preview page. The print preview only shows the title. Here is my code.

$("#task_table_list").DataTable({
        dom: "fBrt",
        buttons: [
            {
                extend: 'copy',
                text: '<i class=" icon-file-openoffice position-left"></i>',
                "className": 'all_button'
            },{
                extend:'pdf',
                text:'<i class="icon-file-pdf position-left"></i>',
                "className": 'all_button'
            },
            {
                extend:'csv',
                text:'<i class="icon-file-excel position-left"></i>',
                "className": 'all_button'
            },
            {
                extend:'print',
                text:'<i class="icon-printer position-left"></i>',
                "className": 'all_button',
                // "autoPrint": false,
                exportOptions: {
                        stripHtml: true
                },
                exportOptions: {
                    modifier: {
                        page: 'current'
                    }
                },
            },

        ]
    })

Answer 1

Here is a working example with the same buttons you have.

Before, here are some things to take into consideration:

1. Make sure that your stylesheets/scripts are in the correct order

<link rel="stylesheet" href="https://cdn.datatables.net/1.11.5/css/jquery.dataTables.min.css">
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/buttons/2.2.2/css/buttons.dataTables.min.css"/>

<script src="https://code.jquery.com/jquery-3.5.1.js"></script>
<script src="https://cdn.datatables.net/1.11.5/js/jquery.dataTables.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jszip/2.5.0/jszip.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.36/pdfmake.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.36/vfs_fonts.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/1.11.5/js/jquery.dataTables.min.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/2.2.2/js/dataTables.buttons.min.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/2.2.2/js/buttons.html5.min.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/2.2.2/js/buttons.print.min.js"></script>

2. In your table declaration, you have the same exportOptions twice, instead of defining them twice, combine them into one like so:

{
                extend:'print',
                text:'Print',
                "className": 'all_button',
                // "autoPrint": false,
                exportOptions: {
                        stripHtml: true,
                         modifier: {
                        page: 'current'
                    }
                },
            },

var dataSet = [
