Ink Jet Printers – They spray tiny drops of ink onto the paper to create the image. The dots are as small as 50 microns. A human hair is about 70 microns for reference, so don’t bother looking for them. For more information about how ink jet printers work we recommend this website: http://www.howstuffworks.com/inkjet-printer.htm
Laser Jet Printers – They use static electricity to stick plastic powder (toner) on the paper and then melt it onto the paper using a hot roller. That’s right, laser jets don’t use ink they use toner which is a very fine plastic powder. For more information about how these printers work I recommend this website: http://computer.howstuffworks.com/laser-printer.htm There are color laser jet printers by the way. They use toner that is black, cyan, magenta and yellow to create all the colors of the rainbow.
