Okay, it looks like OLECMDID_PRINT should be defined as 6. I got that info here:
http://msdn.microsoft.com/library/psdk/com/oen_a2z_22sk.htm

OLECMDEXECOPT_DONTPROMPTUSER should be defined as 2. Got that info here:
http://msdn.microsoft.com/library/psdk/com/oen_a2z_5k38.htm

Give it a try, either by defining those constants, or by just substituting the numbers for the constants in the third line, like so:

oIE.ExecWB( 6, 2, 0, 0)

Good luck,
