A system for enhancing the use of digitized documents as information transmitting and storage objects in connection with an electronic printer having an image input scanner for scanning documents and converting the image content to image signals. In one embodiment, a bar-coded document has an encoded image representing a secret message, and the printer is equipped with a recognition circuit that uses the bar code to distinguish the encoded document from other non-coded documents to be printed and readies a decoder which upon proper authentication, automatically decodes the encoded image signals output by the array so that the printer provides a print with the decoded message. In a second embodiment, the digitized image comprises an auxiliary software program to be loaded into the printer memory, with a selector circuit for loading the software signals output by the array into the printer memory, with a selector circuit for loading the software signals output by the array into the printer memory.
