Profit margins among printer manufacturers are already below 5% even with the current "inflated" ink prices. That suggests that it doesn't make financial sense to enter the market with a lower cost product.
Not challenging you, but I'm curious what source you have for this stat? I'd be interested in a good source for profit margins for many products, and also in the process behind those numbers.
Most large companies are required to disclose profit margins to their investors and shareholders. In Germany, unternehmensregister.de has such info. But in this case, I got the 5% directly from Brother: https://global.brother/en/investor/highlights/finance
