Is it possible to hack an old printer to make it a PC controlled robot?

I have an old HP 882c printer and I want to make it into a PC remote controlled computer.... I want to make a program so that it waves something around in a certain way continuously. Is this possible? Is there some website that would help me do this?

Okay, here's the scenario: Cut a hole in the side of a PC box and shoot a fire extinguisher into it, essentially flash-freezing everything while increasing air pressure. Will the electronics still work? How about the motors in the CD drives, fans, etc.? I'm looking more for advice on how to make this more damaging (or if it'll even work) and less for advice on how to fix it.

When calculating a price level that is one standard deviation from a 100-day-moving average, is the standard deviation calculated using the values of the moving average itself over the last 100 days, or the price values over the last 100 days? In either case, why?

If I had a memory of an event for example, would that be imprinted on the surface/inside of my brain tissue? If you could open up my brain and there was a scanner that could decode the information (like on a computer memory chip) could a computer linked up to the scanner pick up the memory?

Atheists often apply Occam's razor in arguing against the existence of God on the grounds that God is an unnecessary hypothesis. We can explain everything without assuming the extra metaphysical baggage of a Divine Being.

If a function is periodic, with period c, then so is it's derivative.

I know this statement is true, but how do I explain this?? Can anyone help me?

Next question:
If the function f(x)/g(x) is defined but not differentiable at x = 1, then either f(x) or g(x) is not differentiable at x = 1.
Is this statement true or false?? Why??
