I am using vb.net and crystal reports 10

I have a report with parameters that I send to the viewer whic as expected prompts for the parameters and runs fine.
If however I send the same report to the printer using the mrdReportDoc.PrintToPrinter(numCopies, True, 0, 0) function from the report object it firstly does not prompt for any parameters then not surprisingly errors with Missing parametr value.
It also does this if you try and export the report too !

Is this a bug that should be fixed or do I have to live with it and handle the entry of parameters myself. Which I really need to be bothering about at this stage of my project !!

Thanks in advance anyone who replies
