Problem with printing multiple reports in loop

I have a WinForms Application (.net 4.0, x86) with Crystal Reports (13.0.15).

I want to print multiple documents using Crystal Reports (without seeing them on Report Viewer - directly on printer).

foreach(var document in documents )
{
  ReportDocument report=GenerateReport(document.id);
 report.PrintToPrinter(printerSettings, pageSettings,false);
}

Everytime it prints 48 reports and on 49th print I've got exception

System.ComponentModel.Win32Exception The handle is invalid Void OnStartPrint(System.Drawing.Printing.PrintDocument, System.Drawing.Printing.PrintEventArgs)

I tried another set of documents but I still have exception on 49 print.

I tried to change PrintJobLimit to over 9000 but it doesn't help.

Next I tried to dispose report after print:

foreach(var document in documents )
{
 using (ReportDocument report=GenerateReport(document.id))
  {
 report.PrintToPrinter(printerSettings, pageSettings,false);
  }
}

But now program crashes before print 28th report and I cannot catch exception (program stop working). Only in Event Viewer is information about Application Error (Faulting module name: ntdll.dll). I tried different things (and combination of them):

  report.Close();  

 report.Dispose();  

 report=null;

even GC.Collect() after print but it still doesn't work.

Anybody has a solution (an idea)?
