Printing Multiple DataGridView

I am creating a report in vb.net with my DataGrid data and trying to send it to print. But in this project I'm using two DataGrids, one for a Relatori table, and one for the Report table.

The code I usually use for printing a DataGrid would be this:

Private Sub PrintDocument1_PrintPage(sender As Object, e As Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
    Dim g As Graphics = e.Graphics
    Dim PosicaoLinha As Integer = 40
    Dim LinhasPorPagina As Byte = 45
    Dim total As String = String.Empty
    Dim grupo As String = String.Empty
    Dim valor As String = String.Empty
    Dim unidade As String = String.Empty
    'Definições da pagina
    g.PageUnit = GraphicsUnit.Millimeter
    'Desenhar folha
    Dim Titulo As New Font("Arial", 4, FontStyle.Regular, GraphicsUnit.Millimeter)
    g.DrawString("*** Resumo de vendas por Grupo *** ", Titulo, Brushes.Black, 10, 20)

    For L = 0 To LinhasPorPagina - 1
        If LinhaAtual = RELATORIDataGridView.Rows.Count Then Continue For
        For i As Integer = 0 To RELATORIDataGridView.ColumnCount - 5

            If Not RELATORIDataGridView.Item(i, LinhaAtual).Value = Nothing Then
                grupo = RELATORIDataGridView.Item(i, LinhaAtual).Value

            End If
        Next
        For i As Integer = 0 To RELATORIDataGridView.ColumnCount - 3

            If Not RELATORIDataGridView.Item(i, LinhaAtual).Value = Nothing Then
                unidade = RELATORIDataGridView.Item(i, LinhaAtual).Value

            End If
        Next
        For i As Integer = 0 To RELATORIDataGridView.ColumnCount - 4
            RELATORIDataGridView.Columns(4).DefaultCellStyle.Format = "C2"
            If Not RELATORIDataGridView.Item(i, LinhaAtual).Value = Nothing Then
                valor = RELATORIDataGridView.Item(i, LinhaAtual).Value
            End If
        Next
        'Desenhar conteudo na página
        e.Graphics.DrawString("Grupo", New Font("Verdana", 6), Brushes.Black, 20, 30)
        e.Graphics.DrawString(grupo, New Font("Verdana", 6), Brushes.Black, 20, PosicaoLinha)
        e.Graphics.DrawString("Unidades", New Font("Verdana", 6), Brushes.Black, 40, 30)
        e.Graphics.DrawString(unidade, New Font("Verdana", 6), Brushes.Black, 40, PosicaoLinha)
        e.Graphics.DrawString("Valor", New Font("Verdana", 6), Brushes.Black, 60, 30)
        e.Graphics.DrawString(valor, New Font("Verdana", 6), Brushes.Black, 60, PosicaoLinha)
        e.Graphics.DrawString("______________________________________________________________________________________________________________________________", New Font("Verdana", 8), Brushes.Black, 0, 34)
        PosicaoLinha += 5
        LinhaAtual += 1
        valor = String.Empty
        grupo = String.Empty
        unidade = String.Empty
        total = String.Empty
    Next
    e.Graphics.DrawString("Totais: ", New Font("Verdana", 6), Brushes.Black, 20, PosicaoLinha)
    e.Graphics.DrawString(lblTotalUnidade.Text, New Font("Verdana", 6), Brushes.Black, 40, PosicaoLinha)
    e.Graphics.DrawString(lblTotalValor.Text, New Font("Verdana", 6), Brushes.Black, 60, PosicaoLinha)
End Sub

Can anyone tell me how I add another DataGrid in this code for printing?

If I do, I'm using Access as the base.
