would like to know if print preview can be opened in landscape
  mode, because right now, the print preview shows one column in one page and
  other 2 columns in another page.

We have checked the reported scenario
  from our end. The print preview shows properly all columns on one page. We
  are unable to reproduce the reported problem from our end.
  However, your requirement to print the
  data in Landscape in MultiColumnTreeView can be achieved by enabling the
  Landscape property in MultiColumnTreeView.PrintDocument.DefaultPageSettings.
  Refer to the below code snippet,

// Print the MultiColumnTreeView in
    Landscape mode.
    this.multiColumnTreeView1.PrintDocument.DefaultPageSettings.Landscape
    = true;

also, can the window size be changed.

MultiColumnTreeView does not contain
  direct support to change the window size. However, your requirement to change
  the print window of MultiColumnTreeView can be achieved by setting the Width
  and Height of PrintPreviewDialog. Refer to the below code snippet,

// Create the Print Preview Dialog object
    and set the size.
     PrintPreviewDialog dialog = new
    PrintPreviewDialog();
     
     // Set the Window size by assigning the
    Width and Height properties of PrintPreviewDialog.
     dialog.Width = 800;
     dialog.Height =
    700;

the text appears to be slightly blurred in PDF from print
  preview. is there any reason for this?

The reported problem is not an issue.
  It occurs due to the minimum zoom value applied at initial loading in
  PrintPreviewDialog based on the AutoZoom property. 
  However, you can overcome this by
  setting the Zoom property in PrintPreviewControl.PrintPreviewControl. Refer
  to the below code snippet,

//Avoid the text blur by assigning the
    Zoom property to 1.0
    dialog.PrintPreviewControl.Zoom = 1.0;

I would also like to know if its
  possible to add a header to the print preview.

We have
  checked the possibility to achieve your requirement. We regret to inform you
  that there is no way to display the columns header when print preview in MultiColumnTreeView.

Thank you for the reply!The above code snippet shows print preview of the print document and not the full contents of the treeview. I want to change window size of the print preview in the following :multiColumnTreeView1.PrintPriview();Also, is there a way to center-align just a single node?TIA

The above code snippet shows print preview of the print document and not the
  full contents of the treeview. I want to change window size of the print
  preview in the following :

As we mentioned earlier,
  MultiColumnTreeView does not contain direct support to change the window size
  while using the PrintPreview method. Your requirement to show the full
  contents of the MultiColumnTreeView can be achieved by getting the image and
  get the print document using reflection. Refer to the below code snippet,

private void button1_Click(object sender, EventArgs e)
     {            
         // Convert the MultiColumnTreeView to Image.
         multiColumnTreeView1.ToImage();           
     
         // Create the Print Preview Dialog object and set the size.
         PrintPreviewDialog dialog
    = new PrintPreviewDialog();
     
         // Set the Window size by assigning the Width and Height properties
    of PrintPreviewDialog.
         dialog.Width = 800;
         dialog.Height = 700;
     
         // Get the PrintDocument of MultiColumnTreeView using Reflection.
         var document =
    (PrintDocument)this.multiColumnTreeView1.GetType().GetField("m_pdDocument", BindingFlags.Instance |
    BindingFlags.NonPublic).GetValue(this.multiColumnTreeView1);
     
         // Print the MultiColumnTreeView in Landscape mode.
        
    document.DefaultPageSettings.Landscape = true;
     
         // Set the Document to be previewed by assigning the PrintDocument
    property of MultiColumnTreeView.
         dialog.Document = document;            
     
         // Show the dialog to PrintPreview.
         dialog.ShowDialog();
     }

is there a way to center-align
  just a single node?

Your
  requirement to center-align in single node in MultiColumnTreeView can be
  achieved by setting the Alignment as Center for TreeNodeAdvSubItem. Refer to
  the below code snippet,

// Set the Alignment of the first SubItems.
     this.multiColumnTreeView1.Nodes[0].Nodes[0].SubItems[0].Alignment
    = StringAlignment.Center;
     // Set the Alignment of the Second SubItems.
     this.multiColumnTreeView1.Nodes[0].Nodes[0].SubItems[1].Alignment
    = StringAlignment.Center;

Note: The Expander contains a TreeNodeAdv (First Column) that does not
  have alignment support.
