Inventor bug: Submit print does not work when document opened hidded mode

[Anonymous]

If drawing document has been opened in FWxMainFrameEnvironment environment with the hidden mode flag.
DrawingDocument printMe = site.Application.Documents.Open(documentFile, false) as DrawingDocument;
it seems that PrintManager.SubmitPrint() does not print. It does not throw any error this case.

I have the same problem!

Seems the printmanager does not work as the open command does not change the environment properly if the hidden flag is false.

Unfortunately, drawings do need to be open visibly
in order to print them.
