Abstract: A scanning apparatus and a method thereof include a scanning unit scanning a document and outputting a scanned result, at least one external storage unit detachably attached to the apparatus, at least one internal storage unit, and a controller detecting an attachment state of the external storage unit and storing the scanned result in one of the external storage unit and the internal storage unit according to the attachment state of the external storage unit. The scanning unit of the scanning apparatus is combined with a user scanning unit and a user printing unit into a combination apparatus, and the scanned result is printed in a printing apparatus spaced-apart from the scanning apparatus by a distance, thereby removing cables between the scanning or printing apparatus and a personal computer.
