Re: Motherf***ers. I strongly doubt this is the only HP that has done this.
After being asked to support our users home printers a number of years ago (as occasionally used for work purposes), I simply told pointed out a few select facts to the people concerned.
1) An injet cartridge for 150 sheets can cost as much as a second hand (B&W) network printer of the same sort as we already have a few dozen of in the office.
2) We get a bulk buy price on our toner cartidges of about £20, for a cartridge that does ~15,000+ sheets and we'd happily sell users the cartridges for £20 if they ever used the one that came in the machine. We've had one taker so far, who bought a spare cartridge which he'll probably never use.
3) Given that at 150 sheets per month it'll take them about a decade to go through a full cartridge, and well over a century before needing a minor service, i'd happily do any maintenance that might be required.
Surprisingly, every single user said "oh, I don't use colour", probably because people deploy a combination of printing digital photos at asda or doing the odd sheet on our office photocopiers. (which given the 0.16p per page toner cost, i'm sure we can live with)
Unless reminded, I do tend to forget that those printers exist as I never hear anything about them.
