1.) Business Engineering or Manufacturing :)

The correct answer is: Scanner
The scanner is a piece of technology which unlike the printer is an input device which basically scans the top-view of any flat surface (usually paper but is definitely not limited to it) introduced in its effective range using light. The data scanned is then transfered to the Central Processing Unit for futher processing. The processed image can then be outputted and seen on the monitor's display. Once available for printing, the Central Processing Unit will just send the processed image into the printer ad voila, your scanned image is now printed in a piece of paper!
Today, scanners come with printers as a bundle. It is a perfect combination since the printer will just print the image anyway.
It is true because it is really a good practise to save a presentation before printing it

Good business ethics are the key to good marketing and success. Ethics portray whether an individual has good judgment, intelligence, and many more things that are essential to business. Without good ethics business as a whole would be ruthless. Some business ethics are even required by the law in some places and there are rules and regulation to trade.
Hope that answered your question!
