How to setup printer for oleobject?

I use ole object in pb 11.5 like:

OLEObject myoleobject

myoleobject = CREATE OLEObject

result = myoleobject.ConnectToNewObject( "word.application")

......

myoleobject.ActiveDocument.PrintOut

I have setup default printer on Windows XP, but the printing does not go to the default printer.

So before printout, I want to setup printer to print the doc. how to setup printer for oleobject?
