Which of the following is NOT a function of the Barcode Reader?
Answer: D
The function a barcode reader does not perform is to print.
A barcode reader is an input device. It shines light on the pattern of bars, captures and reads the reflected pattern, and decodes it into the numbers or letters it represents, which are sent to the computer, for example at a billing counter.
Capturing, reading and translating the barcode into numerals or alphabets are all its functions. Printing barcodes is the job of a separate output device, a barcode or label printer.
