Re: I want to know
HP Laserjet 1320 desktop printers (about ten years ago) had 130MHz processors. That's about 5 times more power than most people had playing it to start with.
My network printers in use now have 500MHz processors. I do occasionally wonder why they need this level of power, but presumably this comes about because it's cheaper to buy and integrate a cheap mobile phone processor than to create a fab to knock out 486 chips.
