A little bit of background on Printers
Everybody has used printers, at least a few times in their lifetime. It is a remarkable invention. It works by laying a layer of ink on a piece of paper or other materials. Before printing press( the earlier version of printers) were available, the only way of creating documents was by writing manually, which was very costly. So, only the rich could afford books.
