SSRS: Direct Printing to Printer

Sometimes we don't need print preview. How to allow user print directly to a printer without viewing it first on screen. ReportViewer control is needed on this example, but I don't want to modify the existing UI. So we'll also added ReportViewer runtime and make it hidden.
This is report that we want to print:

Arrange control as below:

Then type this code behind:
Imports System.Drawing.Printing 
Imports System.Drawing.Imaging 
Imports System.IO 
Imports Microsoft.Reporting.WinForms

Public Class frmPrintReport
    Dim pages As New List(Of Metafile)
    Dim pageIndex As Integer = 0
    Dim doc As New Printing.PrintDocument()
    Dim ReportViewer1 As New ReportViewer

    Private Sub frmPrintReport_Load(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles MyBase.Load
         
        Button1.Text = "Print"
        With ReportViewer1
            .Visible = False
            .ProcessingMode = ProcessingMode.Remote
            .ServerReport.ReportPath = "/HRD/Attendance Report"
            .ServerReport.ReportServerUrl = New _
                     Uri("http://localhost/ReportServer")
        End With
        Me.Controls.Add(ReportViewer1)

    End Sub

    Private Sub PrintPageHandler(ByVal sender As Object, _
        ByVal e As PrintPageEventArgs)
        Dim page As Metafile = pages(pageIndex)
        pageIndex += 1
        Dim pWidth As Integer = 827
        Dim pHeight As Integer = 1100
        e.Graphics.DrawImage(page, 0, 0, pWidth, pHeight)
        e.HasMorePages = pageIndex < pages.Count
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles Button1.Click
        Dim doc As New Printing.PrintDocument()
        doc = New Printing.PrintDocument()
        AddHandler doc.PrintPage, AddressOf PrintPageHandler
        Dim dialog As New PrintDialog()
        dialog.Document = doc
        Dim print As DialogResult
        print = dialog.ShowDialog()

        doc.PrinterSettings = dialog.PrinterSettings

        Dim deviceInfo As String = _
        "<DeviceInfo>" & _
        "<OutputFormat>emf</OutputFormat>" & _
        "  <PageWidth>8.5in</PageWidth>" & _
        "  <PageHeight>11in</PageHeight>" & _
        "  <MarginTop>0.25in</MarginTop>" & _
        "  <MarginLeft>0.25in</MarginLeft>" & _
        "  <MarginRight>0.25in</MarginRight>" & _
        "  <MarginBottom>0.25in</MarginBottom>" & _
        "</DeviceInfo>"

        Dim warnings() As Microsoft.Reporting.WinForms.Warning
        Dim streamids() As String
        Dim mimeType, encoding, filenameExtension, path As String
        mimeType = "" : encoding = "" : filenameExtension = ""

        'Input parameter report
        Dim DateFrom As Date = CDate("4/15/2015")
        Dim DateTo As Date = CDate("4/15/2015")

        Dim parmDateFrom As New ReportParameter("DateFrom", DateFrom)
        Dim parmDateTo As New ReportParameter("DateTo", DateTo)
        Dim parmSO1(1) As ReportParameter
        parmSO1(0) = parmDateFrom
        parmSO1(1) = parmDateTo

        Dim data() As Byte
        ReportViewer1.ServerReport.SetParameters(parmSO1)
        data = ReportViewer1.ServerReport.Render("Image", _
               deviceInfo, mimeType, encoding, filenameExtension, _
               streamids, warnings)
        pages.Add(New Metafile(New MemoryStream(data)))

        For Each pageName As String In streamids
            data = ReportViewer1.ServerReport.RenderStream("Image", _
                   pageName, deviceInfo, mimeType, encoding)
            pages.Add(New Metafile(New MemoryStream(data)))
        Next
        doc.Print()
        Me.ReportViewer1.RefreshReport()
    End Sub
End Class

Then lets try, I'm using pdf printer to print.
