Not exactly, premines and ICO's are what is actually the same as printing money, but forking is more complex. With forks, people who gain the most are whales, but they are usually concerned about privacy and safety, so they prefer to wait instead of dumping their forked coins asap. And to have a successful fork with some value, you need to build community support for it, by spreading information about it on blogs and social media and pumping its price after it's launched.
