HELP !!!

I have a 10:00 AM Sat, Feb 4 deadline !!!

I'm trying to print the mirror image of Columns A-F from one-side of paper
to columns G-L on the opposite side, but the columns do not match up for
printing so that I can actually paper-cut the columns up into 3-pieces for
cutting.

i.e after cutting they look like follows:
Columns AB CD EF EF CD AB - where AB CD EF are on pg 1 & EF CD AS are on pg 2
