> Computers have gotten MUCH faster at user response.
No. It all depends on what you run on the computer. Maybe you used to run programs that were (relatively) more demanding than what you run now, maybe most programs are now relatively less demanding than most programs were, but it is not the general case that computers have gotten MUCH faster at user response. They've mostly stagnated, barely improved.
> these days the printer has it's own processor and RAM
They've always had that. Actually in the mid-90s my printer was more powerful than my computer. It's just that the printers processors and RAM have vastly improved, too.
