Today I experienced the hell of proprietary, subscription-only HP #printers for the first time.

Not only they require a proprietary #HP account and Windows machine to work, they do not let you print unless you buy ink at ~3000% its value from their subscription service. Buying an old printer nowadays is the only reasonable choice, as they are getting worse and worse.

But non-Linux machines (without Gutenprint) don't support those, because of proprietary drivers!
