printing on both sides?

i made an illustrated catalogue with ps7 and would like to print it. my printer is able to print on both sides. can i print the whole catalogue with two files on one page (back and front) automatically with ps or do i need a layout program? in addition to ps i have installed illustrator and fireworks - could this help?
thx for your help,

I have no idea bout the printing (depends on what kinda printer...how you arranged the pages etc)....but i recomend taking a look at QuarkXpress for layout.
