Answer:
Difference Between Printer and Scanner
Printer vs scanner
Printers and scanners are entirely different devices where a printer is an output device while the scanner is an input device. The notable difference between them is that the printers process the soft copy and produces its hard copy. On the other hand, the scanner does the inverse of the printer where the printed hard copied material is converted into the soft copy.
The working of Printer and scanner is completely opposite where the Printer is used for transforming the electronic document into a physical piece of paper. Conversely, a scanner takes the data from an object such as data over a paper is converted into an electronic document. Although, nowadays all in one device is also available, which is capable of performing all the function that could be performed by a printer, scanner and photocopy machines.
