I'll always remember when our fairly expensive prosumer all-in-one-printer suddenly wouldn't let me scan pages because there was "no more ink" in the printer right before an important task. A straight up scam. I'm surprised no one has disrupted the sad state of affairs in the printer industry yet even though it's slowly dying.
Are we looking for someone to sell an ink-based printer that will cost more up front than its competitors, and then willingly forego the revenue that comes from market ink prices?
