Duplex Print setting in CR XI (VB)

Hi,

I am using CR XI

My code is as below

Dim lrpt As CRAXDRT.Report

Set lrpt = crxApplication.OpenReport(App.Path & "\" & Me.Tag)

With lrpt

.PaperSource = crPRBinAuto

.PrintingStatus.Parent.DisplayProgressDialog = False

.PrintOut (False)

end with

What change I need to do in order to allow duplex printing.

All our printer support duplex printing.

Any help is appreciated.

Thanks,

Reena
