How to call print button in my function

mamadsoli

Hello, how to can call print function in datatables ?
I need to call print function in my custom button...
(without define any print buttons in my page, I only have my custom button)

buttons: [
{
    text: 'My Print Button',
    action: function (e, dt, node, config) {
        // Some code before call print function
        
                // Now call print
        table.printFuction(e, dt, node, config);

        // Some code after call print function
    });
}
]

thanks

Have a look at that last example in the buttons.buttons.action documentation for how to do what you are looking for. DataTable.ext.buttons.print.action is the function you want.

Excuse me, I write this code, but I don't have columns on output.
Can you tell me where's my wrong? thank you

{
text: 'Print All',
className: 'btn btn-light',
action: function (e, dt, node, config) {
    
    config.label= 'Test company';
    config.messageTop= 'Test top message';
    config.messageBottom= 'test bottom';
    config.exportOptions= {
        columns: ':visible',
    };
    config.autoPrint= true;
    
    var totalPage = table.data().count();
    var pageNumber = table.data().page();
    
    var totalRows = table.page.info().recordsTotal;
    table.page.len(totalRows).draw();
    
    table.on('draw', function() {       
        var additionalParams = function() {
            table.off('draw');
            table.page.len(totalPage).page(pageNumber).draw('page');
        };      
        DataTable.ext.buttons.print.action(e, dt, node, config, additionalParams);      
    });
    
    }
},

Its difficult to debug code snippets. Please provide a simple test case replicating the issue so we can help debug.

I found it.
I have to set this code too:

header: true,
footer: true

or

config.header= true;
config.footer= true;

Thank you
