Ignored Paper Size in PrintDialog/XPS Document Writer

Question

I am trying to print with WPF's PrintDialog class (namespace System.Windows.Controls in PresentationFramework.dll, v4.0.30319). This is the code that I use:

private void PrintMe()
{
    var dlg = new PrintDialog();

    if (dlg.ShowDialog() == true)
    {
        dlg.PrintVisual(new System.Windows.Shapes.Rectangle
        {
            Width = 100,
            Height = 100,
            Fill = System.Windows.Media.Brushes.Red
        }, "test");
    }
}

The problem is no matter what Paper Size I select for "Microsoft XPS Document Writer", the generated XPS, always, has the width and height of "Letter" paper type:

This is the XAML code I can find inside XPS package:

<FixedPage ... Width="816" Height="1056">

Changing the paper size in the print dialog only affects the PrintTicket, not the FixedPage content. The PrintVisual method produces Letter size pages, so in order to have a different page size you need to use the PrintDocument method, like so:

private void PrintMe()
{
    var dlg = new PrintDialog();
    FixedPage fp = new FixedPage();
    fp.Height = 100;
    fp.Width = 100;
    fp.Children.Add(new System.Windows.Shapes.Rectangle
        {
            Width = 100,
            Height = 100,
            Fill = System.Windows.Media.Brushes.Red
        });
    PageContent pc = new PageContent();
    pc.Child = fp;
    FixedDocument fd = new FixedDocument();
    fd.Pages.Add(pc);
    DocumentReference dr = new DocumentReference();
    dr.SetDocument(fd);
    FixedDocumentSequence fds = new FixedDocumentSequence();
    fds.References.Add(dr);            

    if (dlg.ShowDialog() == true)
    {
        dlg.PrintDocument(fds.DocumentPaginator, "test");
    }
}
