I'm not sure inkjet printers are a good example, although you can say that since the cheap printers flooded the market there are fewer "good" printers and they lost the economies of scale so they are more expensive.

This example is so polluted by the whole ink cartridge "sell the razor blades" business model and the legal challenges around 3rd party cartridges that I would be very hesitant to generalize from the printer example.

With that said, the kindle business model is that same model so maybe there is something to it.
