An empty report can be produced when loading a report data and printing XtraReport programmatically

[DevExpress Support Team: CLONED FROM Q336182: How to print report direct, and print preview via an simple action?]
Hi,
I have tried this:
Dim reportData As IReportDataV2 = DirectCast(ObjectSpace.FindObject(Application.Modules.FindModule(Of ReportsModuleV2)().ReportDataType, New BinaryOperator("DisplayName", "Bill")), IReportDataV2)
     Dim report = ReportDataProvider.ReportsStorage.LoadReport(reportData)
     With report
        report.RequestParameters = False
        report.Parameters("p_key").Value = hdr.bill_hdr_key

Dim printTool As New ReportPrintTool(report)
        printTool.Print()
     End With
Why is it printing a blank report even if it has properly passed the value of the parameter?  What am I missing?

Hello Voxdei,

As I see, you forgot to call the reportsModule.ReportsDataSourceHelper.SetupBeforePrint(report) method before printing your report.
Please check out the eXpressApp Framework > Task-Based Help > How to: Print a Report Without Displaying a Preview  article for more details.

      Thanks for your help Dennis, I have modified the code accordingly and it works fine now.  The revised code is:
           Dim reportData As IReportDataV2 = DirectCast(ObjectSpace.FindObject(Application.Modules.FindModule(Of ReportsModuleV2)().ReportDataType, New BinaryOperator("DisplayName", "Bill")), IReportDataV2)
           Dim report = ReportDataProvider.ReportsStorage.LoadReport(reportData)
           Dim reportsModule As ReportsModuleV2 = ReportsModuleV2.FindReportsModule(Application.Modules)
           Dim printTool As New ReportPrintTool(report)
           With report
              report.RequestParameters = False
              report.Parameters("p_key").Value = hdr.bill_hdr_key
              reportsModule.ReportsDataSourceHelper.SetupBeforePrint(report)
              printTool.Print()
           End With
