Embedded font doesnt display properly in printdocument

I have some custom fonts that I have embedded in my app.  These work great across all controls, but, my problem arises when I try to use the custom fonts in a printdocument.  The printdocument ends up using the default font, which wont work for what I need.

Here is my sample code, that loads the custom fonts, puts em in a shared font collection to use throughout the app.


            Dim FontNames(3) As String
            FontNames(0) = "LTYPE.TTF"
            FontNames(1) = "LTYPEB.TTF"
            FontNames(2) = "LTYPEBO.TTF"
            FontNames(3) = "LTYPEO.TTF"
            prvFC = Me.GetFont(FontNames)
            Cur.LucidaFonts = prvFC

 Public Function GetFont(ByVal FontResource() As String) As Drawing.Text.PrivateFontCollection
        Try
            'Get the namespace of the application  '  
            Dim NameSpc As String = Reflection.Assembly.GetExecutingAssembly().GetName().Name.ToString()
            Dim FntStrm As System.IO.Stream
            Dim FntFC As New Drawing.Text.PrivateFontCollection()
            Dim i As Integer
            For i = 0 To FontResource.GetUpperBound(0)
                'Get the resource stream area where the font is located '
                FntStrm = Reflection.Assembly.GetExecutingAssembly.GetManifestResourceStream(NameSpc + "." + FontResource(i))
                'Load the font off the stream into a byte array '
                Dim ByteStrm(CType(FntStrm.Length, Integer)) As Byte
                FntStrm.Read(ByteStrm, 0, Int(CType(FntStrm.Length, Integer)))
                'Allocate some memory on the global heap '
                Dim FntPtr As IntPtr = Runtime.InteropServices.Marshal.AllocHGlobal(Runtime.InteropServices.Marshal.SizeOf(GetType(Byte)) * ByteStrm.Length)
                'Copy the byte array holding the font into the allocated memory. '
                Runtime.InteropServices.Marshal.Copy(ByteStrm, 0, FntPtr, ByteStrm.Length)
                'Add the font to the PrivateFontCollection '
                FntFC.AddMemoryFont(FntPtr, ByteStrm.Length)
                Dim pcFonts As Int32
                pcFonts = 1
                AddFontMemResourceEx(FntPtr, ByteStrm.Length, 0, pcFonts)
                'Free the memory '
                Runtime.InteropServices.Marshal.FreeHGlobal(FntPtr)
            Next
            Return FntFC
        Catch ex As Exception
            Dim xx As String = ex.Message
            Return Nothing
        End Try
    End Function


 Private Sub PD1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PD1.PrintPage
        Dim Hfnt As New Font(Cur.LucidaFonts.Families(0), 10, FontStyle.Bold)
        e.Graphics.DrawString("Test Font Print", Hfnt, Brushes.Black, x, y)
End Sub

Note.: on this article, you can select Vb code or Csharp code (default).
For Vb.net code, it uses Marshal.AllocCoTaskMem(fontStream.Length)

I tried this option earlier, the code posted works to write on a form, but, does not work in a printdocument/printpreview.  He also fails to call AddFontMemResourceEx which apparently registers the font with the system.  At this point, I am out of ideas, let me know if you have any thoughts.

I understand.
Print Preview uses metafiles, but d' nt support embebed fonts.
It knows the Font wken you use DrawString, but it d´nt include the font in metafile or Spool.

What are some of the less-than-obvious limitations of Windows metafiles?

Here are a few limitations of metafiles (Windows metafiles (WMF) and/or enhanced metafiles (EMF), as noted) that you might not expect:

Metafiles don't support embedded fonts. This means that if you use a "special" font in a metafile that font won't be displayed on other systems if they don't have that font installed.

Wow, great info, thats what I was looking for.

I guess I will look at installing the fonts instead of embedding.  Thanks for your help!!!
