Hello guidegi,

A possible approach to achieve this might be by handling the 'Printing' event of the 'UltraPrintPreviewDialog' component, cancelling it and showing Microsoft's 'PrintDialog'.

Here is an example code:

        private void ultraPrintPreviewDialog1_Printing(object sender, Infragistics.Win.Printing.PrintingEventArgs e)
        {
            e.Cancel = true;
            printDialog1.ShowDialog();
        }

Please feel free to let me know if a question about our toolset comes up on your mind.
