Abstract
The transmission and reproduction of an original document transferred via a data network can be assured when the printing mechanism generates a unique serial number for the document being printed. The sender of the document is assured that the intended recipient received the document, paid for it, and was able to print it by receipt of the unique serial number and a request for an encryption key by which certain information in the document was encrypted.
