I suppose that you should update your printer driver.
BTW. Let the printer do the imposing, don't do it yourself. If you need to print at home, use the print booklet feature in Acrobat or Reader.
I am using the Print Booklet command in ID.
How do you print booklet from Acrobat? I have not seen that, always done it from ID.
It is found in the pront dialog as an option.
Problem with the print booklet is that you use postscript. But postscript should be avoided: no eps, no pdf via print or distiller.
