You can print a Crystal Report using the print option of Crystal Report Viewer. However, there are occasions when you want your application to print a report directly to the printer without viewing the report in Crystal Report Viewer.
 

The ReportDocument class provides PrintToPrinter method that may be used to print a CR direct to the printer. If no printer is selected, the default printer will be used to send the printing pages to.
 
The PrintToPrinter method takes four parameters.
 
nCopies : Indicates the number of copies to print.
collated : Indicates whether to collate the pages.
startPageN : Indicates the first page to print.
endPageN : Indicates the last page to print.
 
The following steps will guide you to achieve the same:
    Add a crystal report (.cr) file to your ASP.NET application.
    Add a report instance on the page level.
        Dim report As MyReport = New MyReport

    Populate reports data on Page_Init
        ' Get data in a DataSet or DataTable  
          
        Dim ds As DataSet = GetData()  
        ' Fill report with the data  
        report.SetDataSource(ds)

    Print Report
        report.PrintToPrinter(1, False, 0, 0)


If you wish to print a certain page range, change the last two parameters From To page number.
 
If you want to set page margins, you need to create a PageMargin object and set PrintOptions of the ReportDocument.
 
The following code sets page margins and printer name:
    Dim margins As PageMargins =  Report.PrintOptions.PageMargins  
       margins.bottomMargin = 200  
       margins.leftMargin = 200  
       margins.rightMargin = 50  
       margins.topMargin = 100  
       Report.PrintOptions.ApplyPageMargins(margins)  
       
       ' Select the printer name  
       Report.PrintOptions.PrinterName = printerName
