COM doesn't know anything about None.  That's strictly a Python invention.

Very interesting!  So, in the type library, it's NOT declared as an
IDispatch *, but rather as a void *.  If the parameter is allowed to
take arbitrary pointers, and not just COM objects, then I'm not sure
there is a good solution for this.  You can certainly modify the
makepy-generated wrapper file by hand and change the defaults from 0 to
None.

If it's supposed to be a COM object always, then HP should probably
update their type library.
