Alignment problem while printing

hi all

am trying to print "subjects " in a vertical manner and am using a print document to do this
Private Sub prtDocSP_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles prtDocSP.PrintPage

Dim x As Single = e.MarginBounds.Left
Dim y As Single = e.MarginBounds.Top
Dim verticalFormat As New System.Drawing.StringFormat (StringFormatFlags.DirectionRightToLeft.DirectionVertical)

x = 70
y = 250
strPrintLine = "Subjects "
e.Graphics.DrawString(strPrintLine, fntBHeading, Brushes.Black, x, y, verticalFormat)

end sub

it is displaying the text in vertical but i need it to be displayed in the other way. right now the text can only be read from the left hand side, i need to read the text from the right hand side.

Thanks
