Modifying PrintParameters

[BobbyC.Jones]

I'm having trouble setting PrintParameter values.  The following code runs, and the PrintSetup saves, but the PageOrientation value never changes to Portrait.  What am I missing?  Thanks.

Document activeDoc = commandData.Application.ActiveUIDocument.Document;

var trans = new Transaction(activeDoc, "PrintSettings"); 
trans.Start();

activeDoc.PrintManager.PrintSetup.CurrentPrintSetting.PrintParameters.PageOrientation = PageOrientationType.Portrait;

activeDoc.PrintManager.PrintSetup.SaveAs("MyPrintSettings");

PrintSetting myPs = activeDoc.GetPrintSettingIds().
                    Select(activeDoc.get_Element).
                    Cast<PrintSetting>().
                    FirstOrDefault(printSetting => printSetting.Name == "MyPrintSettings");

activeDoc.PrintManager.PrintSetup.CurrentPrintSetting = myPs;
trans.Commit();

A quick perusal through the ADN knowledge base and the answer is found.  Apparently each call to a Document's PrintManager property generates a new PrintManager object.  It needs to be cached and all calls should be made to the cached object.

PrintManager pm = activeDoc.PrintManager;

pm.PrintSetup.CurrentPrintSetting.PrintParameters.PageOrientation = PageOrientationType.Portrait;
