Decades of innovation that have been invested, not to make a better product, but mostly on how to extract more and more money from their victims, I mean "customers".
I would like to own a printer again, but for printing something like once a month, I just can't financially justify spending several hundred bucks on a device that might, at the whim of the manufacturer, decide that the way I'm using it is not okay anymore, is probably designed to break after two years, requires me to sign up for a subscription service for ink, or whatever BS else the decision makers in this space come up with.
There's no room left for innovation or competitive advantage. Its a commoditized market where they only make money when you buy their supplies so naturally they will engineer the product to work well with their supplies only.
This might be an opportunity for open source printer components. Maybe someone can create replacement parts to take out the "brain" of a small printer and replace that with a connected Raspberry Pi that doesn't change the print quality or reject 3rd party cartridges. I know there's likely a lot of settings in the software for head movement, ink usage, etc. so that might take some (possibly illegal?) reverse engineering. I'm a web software person so that idea may sound stupid to someone more knowledgeable.
What? A hackable, OSS printer whose manufacturer puts time and effort into reducing waste and creating the best, longest lasting ink on the planet would crush it.
Well, maybe not. But anytime anyone has said: “That’s it. There’s nothing more to do here.” It tells me there’s a complacent market ripe for disruption.
