Question about printing & margins
 

I am making planner pages to put in a 8 1/2 x 5 1/2 3 ring binder so that
would be 2 pages per reg 8 1/2 x 11 paper. I need to print front and back so
how do I set up the margins correctly? I print one side then flip paper and
print the other side then I cut the paper in half but when I punch the holes
they are in the correct margin area on 1 side of the paper but they aren't on
the opposite side. I hope that makes sense.
