Thank you for writing.
In order to customize the paper size you should specify the RadPrintDocument.DefaultPageSettings.PaperSize
property. Here is a sample code snippet:
sender, EventArgs e)
(radGridView1.RowCount == 0)
RadPrintDocument d =
d.AssociatedObject = radGridView1;
You can find additional information in our Telerik Presentation Framework >> Printing Support >> RadPrintDocument
section in the online documentation.
I hope this information helps. Should you have further questions, I would be glad to help.
