Everyone should have used a printer in their lifetime. Whether at home for a school report or at school for a club poster, printers have become essential for all sorts of work related assignments. What may seem like a trivial task for such a big machine to finish actually is a very complex process using static electricity. Watch the clip below to see how it works (start at 1:52)

  2. Why would your paper feel warm coming right out of the printer? 
  3. How do you think the process for color printers differs?
