Hold a single coupon bond paper in front of you and fold it crosswise. The basic book format with four different pages, which is technically known in publishing circles as a signature. Microsoft Publisher will not print that entire signature automatically, which means you have to feed the first side to your printer, then turn the paper over to the other side in order to print Page 3 and 4. This can be very confusing at first, but if you mark your pages with a pencil, you will soon be able to anticipate on what page exactly your printer will print. Nonetheless, I will not dwell too much on this since you might have opted to use a totally different desktop publishing software.
Desktop publishers can work in different ways.
One brand might not have the feature that the other has, and so on. If you don't know much about computers, I advise you to just visit the desktop publishing people at the nearest shopping mall and ask them to print out those pages for you. The advantage of printing your own book is that you can print as many copies as you can. The downside of course is that you have to anticipate your orders well ahead of time, plus you have to stock up on paper and printer ink. Even then, that scenario is still so much better than paying a publisher for a minimum print run.
