Abstract

A system and method for providing secure, on-demand delivery and retrieval of documents, messages and the like utilizing an adaptor and a printer coupled to the Internet. An adaptor is coupled between a network based printing protocol enabled device, such as, for example, an Internet Printing Protocol enabled printer, and the Internet. A mobile device communicates with the adaptor to allow a user to log onto a document delivery system, via the Internet, and select a document, message or the like to be printed. The adaptor or mobile device provides the Internet address of the printer to the data center, which then sends the selected documents to the printer through the adaptor using the network based printing protocol. Alternatively, the data center can encrypt the documents before sending. A corresponding decryption key is used by the adaptor to decrypt the documents prior to sending to the printer.
