How can I flip / rotate PrintDocument in .NET?

I have a document that I want to flip / rotate 180 degrees when printing. (This is due to the orientation of the label stock in the printer).

There is a property PrintDocument.PrinterSettings.LandscapeAngle, but it is read-only.

I think that this property is affected by the printer driver, and therefore it is not "configured".

Is there a good way that I can rotate print 180 degrees without doing anything contrary?

I think it depends on what you define as “something too nasty” :-)

/ PrintDocument VB.NET DefaultPageSettings

Dim WithEvents mPrintDocument As New PrintDocument
Dim mPrintBitMap As Bitmap
Private Sub m_PrintDocument_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles mPrintDocument.PrintPage
    mPrintBitMap.RotateFlip(RotateFlipType.Rotate90FlipNone)
    mPrintDocument.PrinterSettings.DefaultPageSettings.Landscape = True
    ' Draw the image centered.     
    Dim lWidth As Integer = e.MarginBounds.X + (e.MarginBounds.Width - mPrintBitMap.Width) \ 2
    Dim lHeight As Integer = e.MarginBounds.Y + (e.MarginBounds.Height - mPrintBitMap.Height) \ 2

    e.Graphics.DrawImage(mPrintBitMap, lWidth, lHeight)
    ' There only one page.   
    e.HasMorePages = False
End Sub
Private Sub B_print_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles B_print.Click
    ' Copy the form image into a bitmap.    
    mPrintBitMap = New Bitmap(Me.Width, Me.Height)

    lRect.Width = Me.Width
    lRect.Height = Me.Height

    mPrintDocument.Print()

, GDI, ? :

                _currentPage = Image.FromStream((MemoryStream)_queue.Dequeue());
                pageHeight = _currentPage.Height;
                pageWidth = _currentPage.Width;

                if (pageHeight < pageWidth)
                {
                    _currentPage.RotateFlip(RotateFlipType.Rotate90FlipNone);
                    pageHeight = _currentPage.Height;
                    pageWidth = _currentPage.Width;
