Hi

what kind of printer you are printing on? I assume only ps and pdf 
printers will understand this (to me until now unknown) option.
On the other hand it's possible only special content, as pdf, may be 
printed using this option succsessfully.
I would install a pdf output printer and test the effect of the option 
in the outputted pdf.
