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.

I already have
http://www.todayinsci.com/cgi-bin/indexpage.pl?http://www.todayinsci.com/F/Fellows_Alvin/FellowsTapeMeasurePatent.htm

And the wic-o-pedia http that led me to the above patent application by Alvin J. Fellows in 1868.

Specifically links about prior models of spring loaded tape measures.

Thanks

why do modern engineers & scientists prefer binary number system to other number systems although we have so many number systems & most importantly binary number system is not found in nature? Secondly, although the human mind can comprehend much higher(read: more complex) number systems then why can't we design digital systems on such higher platforms?.... I mean what are the discrepancies in other number systems?

In a Classification 1, Division 2 area, can batteries be installed and operated, or do they need to be issolated? I can't find anything about it in the NEC. I assume they are ok, since they do create a Class 1, Div 2 area under the right circumstances.

By the way, the system voltage is 12V so there is not a large potential.
