Problem printing duplex even though it's saved in the Crystal Report.

I'm using VS.NET 2010 with Crystal Reports 13.0.10.1385

We have a set of Crystal Reports that were created with Crystal 8.5 and they print duplex and the printer and printer preferences are saved with each Crystal Report.

The problem is this, I'm pulling in these reports to my VS.NET 2010 Project using Crystal Report Viewer and it will not keep the printer preferences when you print the report.  Why, it works using VB6.0?  The only way I can get it to print duplex is to manually set the printer preferences before printing the report.
