正确使用PrintPreview对话框

Question

这是我第一次使用打印预览而感到困惑，所以我需要一个建议：

这是我要打印的对话框：

这是我目前在PrintPreview对话框中的显示方式（搞砸了）：

这是我目前的完整代码：

Public Class frmPRINT

Private Sub btnPrint_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    PrintDocument1.Print()
End Sub
Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage

    Dim bm As New Bitmap(DataGridView1.Width, DataGridView1.Height)
    DataGridView1.DrawToBitmap(bm, New Rectangle(0, 0, DataGridView1.Width, DataGridView1.Height))
    e.Graphics.DrawImage(bm, 0, 0)

End Sub

Private Sub btnPrintPreview_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrintPreview.Click

    PrintPreviewDialog1.WindowState = FormWindowState.Normal
    PrintPreviewDialog1.StartPosition = FormStartPosition.CenterScreen
    PrintPreviewDialog1.ClientSize = New Size(600, 600)

    PrintPreviewDialog1.Document = PrintDocument1
    PrintPreviewDialog1.ShowDialog()
End Sub
End Class

我该如何正确设置呢？
