Have you ever wondered why a lot of printers targeted for home and small office consumers are cheaply priced? You may not be aware of it, but it is an open secret in the printer manufacturing industry that printer manufacturers deliberately peg their prices of their printers down. The reason why they could afford to do so is that they fully expect to make up for their unrealized profits with the price of their printer ink cartridges.
It totally makes sense from a business point of view. When you buy a particular printer model, you are committed to buying the printer ink cartridges specifically made for it, no matter how expensive they are. And printer ink indeed are expensive. This can feel a bit oppressive when it seems that you have no choice but to buy costly ink cartridges in order to keep using your printer.
