Hi,

<pre lang="text">
 Public Sub PrintReceipt()
        ''Start Print Receipt

        Dim fh As IntPtr
        Dim SW As IO.StreamWriter
        Dim FS As IO.FileStream
        fh = Win32API.CreateFile("LPT1:", Win32API.GENERIC_WRITE, 0, 0, Win32API.CREATE_ALWAYS, 0, 0)
        ''This one works fine
        ''fh = Win32API.CreateFile("C:\test.txt", Win32API.GENERIC_WRITE, 0, 0, Win32API.CREATE_ALWAYS, 0, 0)
        Dim sfh As New Microsoft.Win32.SafeHandles.SafeFileHandle(fh, True)
        FS = New IO.FileStream(sfh, IO.FileAccess.ReadWrite)
        FS.Flush()
        SW = New IO.StreamWriter(FS)
        SW.WriteLine("ABC Shop")
        SW.WriteLine("Kandy")
        SW.WriteLine("045-2256398")
      
        SW.WriteLine("")
        SW.WriteLine(lblDate.Text & "               " & CurrentUsername & "               " & "Bill No" & lblBillNo.Text)
       SW.WriteLine("--------------------|--------------------") 

        Dim Count As Integer

        While (Count < dtSales.Rows.Count)

            SW.WriteLine(dtSales.Rows(Count).ItemArray(1).ToString)

            SW.WriteLine(dtSales.Rows(Count).ItemArray(0).ToString & " " & dtSales.Rows(Count).ItemArray(2).ToString & " " & dtSales.Rows(Count).ItemArray(4).ToString & " " & dtSales.Rows(Count).ItemArray(5).ToString)



            Count = Count + 1

        End While
        SW.WriteLine("")
        SW.WriteLine("----------------------------")
        SW.WriteLine("")
        SW.WriteLine("Thank You")
        FS.Flush()
        SW.Close()
        FS.Close()
        sfh.Close()


        ''End Print Receipt
    End Sub
