After you have the paper resized, and the patterns re-aligned, you should be able to print. There are a few more things that you may want to change before printing though.
You can change whether or not there are flaps (which are used to tape or glue one pattern to the other), color the flaps, or change the width of the flaps.
You can turn on or off the Edge ID- it's a number that helps you match adjacent edges. From here you can also flip the ID position and change the font size. Size 6 font will reduce the chance of numbers overlapping.
Here you can edit appearance of your line, if it is a Cut Line, Mountain Line (outside fold) or Valley Line (inside fold). Knowing the overall look of your Mountain and Valley lines will help you know whether you are folding out or folding in. If you are not satisfied with the line type defaults, you can also change them to your preference.
