Hi Lee,

In order to achieve this you need to customize the settings of the print dialog - the following code snippet shows how to create your own print dialog and update the printer manager settings:

   NPrintManager pm = new NPrintManager(nChartControl1.Document);

   using (PrintDialog dlg = new PrintDialog())
   {
    dlg.UseEXDialog = true;

    PrinterSettings settings = (PrinterSettings)pm.PrinterSettings.Clone();
    settings.MinimumPage = 1;
    settings.MaximumPage = 10;
    settings.FromPage = 1;
    settings.ToPage = 1;
    settings.Copies = 2;
    settings.PrintRange = PrintRange.Selection;

    dlg.AllowSomePages = true;
    dlg.PrinterSettings = settings;

    if (dlg.ShowDialog() == DialogResult.OK)
    {
     pm.PageSettings.PrinterSettings = dlg.PrinterSettings;
     pm.PrinterSettings = dlg.PrinterSettings;
    }
   }

Hope this helps - let us know if you meet any problems...
