FYI I'm Mac-based.

I've used InDesign's data merge feature to number a bunch of gift certificates, then used Quick Imposition Plus to impose the document to send to the printer. I used the n-up option to print three certificates on each letter-sized paper.

However, is there a way to send it to the printer so when cut the stack of papers would stack on top of each other in number order?

If some could point me in the right direction that would be great or give me any recommendations (software, methods, etc.)
