I have WPF window that i want to Print on paper size **4inch by 6inch**

I have WPF window that i want to Print on paper size 4inch by 6inch.

i dont understand where to set this size?? i am using window size to print but window size its not working. my printer is not fixed paper size.
this is my print code:

private void _print()
    {
        PrintDialog printDlg = new System.Windows.Controls.PrintDialog();
        //printDlg.ShowDialog();
        //get selected printer capabilities
        System.Printing.PrintCapabilities capabilities = printDlg.PrintQueue.GetPrintCapabilities(printDlg.PrintTicket);

        //get scale of the print wrt to screen of WPF visual
        double scale = Math.Min(capabilities.PageImageableArea.ExtentWidth / this.ActualWidth, capabilities.PageImageableArea.ExtentHeight /
                       this.ActualHeight);

        //Transform the Visual to scale
        this.LayoutTransform = new ScaleTransform(scale, scale);

        //get the size of the printer page
        Size sz = new Size(this.ActualWidth, this.ActualHeight);

        //update the layout of the visual to the printer page size.
        this.Measure(sz);
        this.Arrange(new Rect(new Point(capabilities.PageImageableArea.OriginWidth,  capabilities.PageImageableArea.OriginHeight), sz));

        //now print the visual to printer to fit on the one page.
        printDlg.PrintVisual(this, "Print Page");
    }

You can also adjust the Visual with respect to the paper size. This code adjusts the image to 4x6 inch paper.

        var photo = new BitmapImage();
        photo.BeginInit();
        photo.CacheOption = BitmapCacheOption.OnLoad;
        photo.UriSource = new Uri(photoPath);
        photo.EndInit();

        bool isPortrait = photo.Width < photo.Height;
        if (isPortrait)
        {
            var transformedPhoto = new BitmapImage();
            transformedPhoto.BeginInit();
            transformedPhoto.CacheOption = BitmapCacheOption.OnLoad;
            transformedPhoto.UriSource = new Uri(photoPath);
            transformedPhoto.Rotation = Rotation.Rotate270;
            transformedPhoto.EndInit();

            photo = transformedPhoto;
        }

        int width = 6;
        int height = 4;

        double photoScale = Math.Max(photo.Width / (96 * width), photo.Height / (96 * height));

        var vis = new DrawingVisual();
        var dc = vis.RenderOpen();

        dc.DrawImage(photo, new Rect
        {
            Width = photo.Width / photoScale,
            Height = photo.Height / photoScale
        });

        dc.Close();

        var pdialog = new PrintDialog();
        pdialog.PrintTicket.PageOrientation = PageOrientation.Landscape;
        pdialog.PrintTicket.PageBorderless = PageBorderless.Borderless;

        pdialog.PrintTicket.PageMediaSize = new PageMediaSize(PageMediaSizeName.NorthAmerica4x6);
        pdialog.PrintTicket.Duplexing = Duplexing.OneSided;
        pdialog.PrintTicket.CopyCount = 1;
        pdialog.PrintTicket.OutputQuality = OutputQuality.Photographic;
        pdialog.PrintTicket.PageMediaType = PageMediaType.Photographic;

        pdialog.PrintQueue = new PrintQueue(new PrintServer(), PrinterName);
        pdialog.PrintVisual(vis, "My Visual");

In WPF 1 unit = 1/96 of inch, so you can calculate your size in inches using this formula

you can set printDlg.PrintTicket.PageMediaSize to the size of the Paper and then transform your window to print in that area as below:

 private void _print()
 {
      PrintDialog printDlg = new System.Windows.Controls.PrintDialog();

       PrintTicket pt = printDlg.PrintTicket;
       Double printableWidth = pt.PageMediaSize.Width.Value;
       Double printableHeight = pt.PageMediaSize.Height.Value;

       Double xScale = (printableWidth - xMargin * 2) / printableWidth;
       Double yScale = (printableHeight - yMargin * 2) / printableHeight;


        this.Transform = new MatrixTransform(xScale, 0, 0, yScale, xMargin, yMargin);


    //now print the visual to printer to fit on the one page.
     printDlg.PrintVisual(this, "Print Page");
}
