How to set printing properties for Sybase.DataWindow.Wpf.DWDataWindowControl from c# code?

We use Sybase.DataWindow.Wpf.DWDataWindowControl version 12.5 for printing reports from c# code. The problem is that DWDataWindowControl do not accept printing properties settings from c# code except margin settings.

this.dwObject.Object.DataWindow.Print.PageRange = "1"; // this do not work

dwObject.Print(true, false);

Print always all pages.

Any help is appreciated.
