摘要： A method for securing data in hardcopy documents. The method includes obtaining a page image having a private data item; generating an encrypted version of the private data item; obtaining a decoder identification (ID) value of a decoder; generating, using an encoder, a symbol having the encrypted version of the private data item and the decoder ID value; and generating a hardcopy document by recording the symbol on a physical medium, where the hardcopy document is transported to a subsystem having the decoder, and where the subsystem decrypts the encrypted version of the private data item after extracting the encrypted version of the private data item from the symbol.

摘要： A print job canceling method for a printer is described and is especially useful in a printer with relatively small buffer memory. When a print job is cancelled by the user using the printer's control panel, this method allows the printer controller to receive additional print jobs while the current job is being cancelled, without having to notify the host to stop sending the current print job. The printer controller reduces the memory allocated to the job being cancelled. The printer controller continues to accept data for the current job from the host, but does not print the received data. The data is subsequently flushed from the memory. The printer controller also assigns a lower priority to the print job being cancelled. Meanwhile, the remaining memory can be used to receive and print additional print jobs.

摘要： A method for restricting duplication of a hardcopy document, including: displaying, in response to a request to print a document from a user application, a graphical user interface (GUI); receiving, in response to displaying the GUI, a plurality of print settings and a plurality of copy restrictions selected from the GUI by a user; generating a copy code by encoding the plurality of copy restrictions; generating a print job for the document based on the copy code and the plurality of print settings; and sending the print job to a print queue to generate the hardcopy document, where the hardcopy document includes a machine-readable version of the copy code, and where the copy code restricts duplication of the hardcopy document by a copier after the copier identifies the machine-readable version of the copy code on the hardcopy document.
