Printing Doesn't Print at the specified location

Question

I use the following code to print text "A" at 100,200 (Points), But it prints at 114,180, What is wrong with my code?

Imports System.IO

Imports System.Drawing.Printing

Public Class Form1

    Public egraphics As Graphics

    Public prnDocument As New System.Drawing.Printing.PrintDocument

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim psize As New Printing.PaperSize("A4", 842, 595)

        AddHandler prnDocument.PrintPage, AddressOf PrintPage

        prnDocument.DefaultPageSettings.PaperSize = psize

        prnDocument.DefaultPageSettings.Margins.Top = 0

        prnDocument.DefaultPageSettings.Margins.Left = 0

        prnDocument.DefaultPageSettings.Margins.Bottom = 0

        prnDocument.DefaultPageSettings.Margins.Right = 0

        prnDocument.OriginAtMargins = True

        prnDocument.Print()

    End Sub

    Private Sub PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs)

        Dim fReportFont As System.Drawing.Font

        egraphics = e.Graphics

        egraphics.PageUnit = GraphicsUnit.Point

        fReportFont = New System.Drawing.Font(Trim("Helvetica"), 60, FontStyle.Regular)

        egraphics.DrawString("A", fReportFont, New SolidBrush(Color.Black), 100, 200)

    End Sub

End Class
