Copying devices are machines that create duplicates of documents or images. Common types include photocopiers, printers, and scanners. These devices can produce physical copies on paper or digital copies that can be stored on a computer or shared online. Most copying devices work by capturing the original document's content and reproducing it. For instance, a scanner converts a physical document into a digital format, while a photocopier uses light and heat to print a paper copy. These devices are widely used in offices, schools, and homes for various tasks, such as printing reports or copying important papers.
