I've has a HP laser printer for a year or so. It's worked fine. It's better than the inkjet it replaced.

Yet recently HP decided that it's absolutely essential I only use HP toner - so kindly forced an update which stopped me using toner from anyone else - including the toner currently in the printer which works perfectly fine.

Luckily I've managed to downgrade the firmware again.

I of course will not be buying a HP product of any kind ever again, given the contempt with which they treat their customers.
