Why does printing always start with 200 copies?

This is just a general situation, the purpose is to maximize the value. You can print less than 200 copies, but the unit price will definitely be much more expensive. In addition, if the quantity is too small, the start-up fee will be added, which is not as good as more than 200 copies. In addition, printing machines generally have a starting fee, that is, at least higher than the starting fee, and the price below the starting fee should also be calculated according to the starting fee, so it is generally 200 copies.
