After testing with printing to file it seems that CS4 "Printer manages color" and "No color management" is identical in Windows (and probably CS5 "Printer manages color" also). So ACPU is actually not needed in Windows. But in OS X, as experts wrote here, there are some API things between application and printer driver and this will not work. I found one trick that will help ACPU print targets in correct size: just set scaling to 104% in printer driver. Thanks
