How to Print a Crystal Report Programmatically in ASP.NET?

 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 the 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:

1. Add a crystal report (.cr) file to your ASP.NET application.
2. Add a report instance on the page level.
   1. Dim report As MyReport = New MyReport 

3. Populate reports data on Page_Init 
   1. ' Get data in a DataSet or DataTable  
   2.   
   3. Dim ds As DataSet = GetData()  
   4. ' Fill report with the data  
   5. report.SetDataSource(ds) 

4. Print Report
   1. 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:

1. Dim margins As PageMargins =  Report.PrintOptions.PageMargins  
2.    margins.bottomMargin = 200  
3.    margins.leftMargin = 200  
4.    margins.rightMargin = 50  
5.    margins.topMargin = 100  
6.    Report.PrintOptions.ApplyPageMargins(margins)  
7.    
8.    ' Select the printer name  
9.    Report.PrintOptions.PrinterName = printerName
