Say I have some sheets in excel that are in different files. I have to do lists for week 1-12 for something. Each one is saved in a different file. I want to print it all out at once so that I can take advantage of duplex printing. Is there a way to make Excel print out all my sheets at once so that I dont have to print one by one, while manually turning over the pages after each sheet so that I can print on both sides?
