Printing in CardView was not supported until NetAdvantage v8.2. So in order to maintain backward compatabiilty, we added a property to enable printing in CardView mode. So, assuming you are using v8.2 or higher, you just have to enable CardView printing like so:

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            UltraGridLayout layout = e.Layout;

            layout.AllowCardPrinting = AllowCardPrinting.RootBandOnly;
        }

Note that printing in CardView mode is only supported for the root band, you cannot print child bands in CardView mode.
