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:
  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
  1. Populate reports data on Page_Init
    1. ' Get data in a DataSet or DataTable
    3. Dim ds As DataSet = GetData()
    4. ' Fill report with the data
    5. report.SetDataSource(ds)
  1. 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)
  8. ' Select the printer name
  9. Report.PrintOptions.PrinterName = printerName
