VB.Net - Print components in a Form

Hi,
I have to print blank pages with some compay info.
The form information prints ok but it is also printing the form background (greyed).
Can someone help to maky this form only prints the desired information without the Form 'greyed' background?

This is the code I am using:

Private Sub btnPrintDatos_Click(sender As Object, e As EventArgs) Handles btnPrintDatos.Click

        If btnImpresora.Text = "Favor seleccione Impresora..." Then
            MsgBox("Favor seleccione una impresora")
        Else

            Dim folio_inicio, folio_final As Integer
            Dim impresora As String
            impresora = btnImpresora.Text
            folio_inicio = txtFolioInicio.Text
            folio_final = txtFolioFinal.Text

            For x = folio_inicio To folio_final

                txtFolioActual.Text = x
                'hacemos invisibles los controles que no deseamos que aparezcan
                btnPrintDatos.Visible = False
                lblFolioInicio.Visible = False
                lblFolioFinal.Visible = False
                txtFolioInicio.Visible = False
                txtFolioFinal.Visible = False
                lblImpresora.Visible = False
                btnImpresora.Visible = False

'I tried using the follow piece of code to hide the form background but it failed :(
                Me.TransparencyKey = Me.BackColor
                Me.AllowTransparency = True
                Me.BackColor = Me.TransparencyKey

                lblFolioActual.Focus()

                'actualizamos el formulario, para actualizar el folio actual
                PrintForm1.Form.Update()

                'configuramos la impresora
                Me.PrintForm1.PrinterSettings.PrinterName = impresora

                'define Margins
                PrintForm1.PrinterSettings.DefaultPageSettings.Margins = New System.Drawing.Printing.Margins(0, 0, 0, 0)

'we now print!
PrintForm1.Print(Me, PowerPacks.Printing.PrintForm.PrintOption.CompatibleModeClientAreaOnly)


                'hacemos visible los controles nuevamente
                Me.Visible = True
                btnPrintDatos.Visible = True
                lblFolioInicio.Visible = True
                lblFolioFinal.Visible = True
                txtFolioInicio.Visible = True
                txtFolioFinal.Visible = True
                lblImpresora.Visible = True
                btnImpresora.Visible = True

            Next x
            MsgBox("Impresion terminada hermano, que tengas un gran día :)")
        End If

    End Sub

    Private Sub btnImpresora_Click(sender As Object, e As EventArgs) Handles btnImpresora.Click
        Dim impresora As String = PrintDialog1.ShowDialog()
        Dim impresora_nombre As String = PrintDialog1.PrinterSettings.PrinterName
        btnImpresora.Text = impresora_nombre
    End Sub

change the background of the form to white just before the print, and restore its background afterwards.

It displays an error on "Me.Background". It says "Not a memeber of Form1"

'define Margins
                PrintForm1.PrinterSettings.DefaultPageSettings.Margins = New System.Drawing.Printing.Margins(0, 0, 0, 0)

                Dim defaultColor As Color = Me.Background 'here is the error displayed

i actually try this code with our office printer and it looks fine.
do the font looks different when u print in grey rather than in white background?

José PerezAuthor Commented:
no, it sees the same but when the form was printing in gray I didn't notice.

If I attached a zip file for you to try in your printer would please check?

It did not allow me to upload the file due to site restrictions so I uplodad a pdf rendition of the final printing. There you can also see that it is 'blurry'.
