The printer may additionally print buyer information on coupons and return information on receipts, slips, and journals. Return information, such as purchase date and location, may be encoded as a bar code label to be scanned upon return.

Abstract: A point-of-sale data terminal device includes an optical scanning device mounted in one of the wall portions of the terminal device. In one embodiment of the invention, the scanning device is mounted in a support member which in turn extends outwardly from and is rotatably mounted in the wall portion enabling the support member to be oriented in a plurality of scanning positions. In a second embodiment of the invention, one or more scanning devices are mounted flush with a wall portion to project scanning light beams in a vertical and/or horizontal direction outwardly from the terminal device.
