WPF / C# printing

[game4tress]

Hi,

I'm trying to print a document in landscape, but i'm only being able to print it in portrait.
I've searched for the problem but i haven't found a solution to the problem.
Can you, please help?
Here's the source code:

public void btnImprimir_Click()
{
    try
    {
        PrintDialog pDialog = new PrintDialog();
        pDialog.PrintQueue = System.Printing.LocalPrintServer.GetDefaultPrintQueue();
        pDialog.PrintTicket = pDialog.PrintQueue.DefaultPrintTicket;


        // set default paper size or remove this line to use the default size 
        pDialog.PrintTicket.PageMediaSize = new System.Printing.PageMediaSize     
            (System.Printing.PageMediaSizeName.ISOA4Rotated); 

        Nullable<Boolean> print = pDialog.ShowDialog();
        if (print == true)
        {
            W.MyFlowDocument.PageWidth = 2950;
            W.MyFlowDocument.PageHeight = 2100;
            DocumentPaginator myDocumentPaginator = ((IDocumentPaginatorSource)W.MyFlowDocument).DocumentPaginator;
            //myDocumentPaginator = new DocumentPaginatorWrapper(myDocumentPaginator, new System.Windows.Size(750, 1200), new System.Windows.Size(48, 48));
            myDocumentPaginator = new DocumentPaginatorWrapper(myDocumentPaginator, new System.Windows.Size(2950, 2100), new System.Windows.Size(48, 48));
            myDocumentPaginator.PageSize = new System.Windows.Size(2950, 2100);

            pDialog.PrintDocument(myDocumentPaginator, "Test");
        }
    }
    catch (Exception err)
    {

    }
}
