In current's globe there is no one who is unaware about the new technologies, no matter the person is educated or not. One of the technological products which are in excess utilize from previous 200 years is the Xerox device which in turn after on overtook through the printers. But together the devices even exists still now just because they both functions the similar functions but from different sources. However I am personally so much impressed through the printer, the way it functions and helps us through giving us the output within a seconds. in fact as years are passing their size are simultaneously decreasing.
