A method of searching for missing resources associated with an image forming apparatus, which includes the steps of: forwarding a print job having a resource call-out from a host computer to an image forming apparatus; receiving the print job on the image forming apparatus; checking the image forming apparatus for a resource, which has been called out by the print job, and if the resource is not available on the image forming apparatus, obtaining the resource by: sending a request for the resource from the image forming apparatus to a device having the resource; receiving a response from the device having the resource indicating that the resource is a non-sharable resource and including at least one link to where the non-sharable resource can be obtained; and choosing a link having the non-sharable resource and obtaining the non-sharable resource.

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.

A method of managing plural print jobs is disclosed, the method includes receiving two or more print jobs on an image forming apparatus; dividing each of the two or more print jobs into a plurality of sub-print jobs for printing by a print engine of the image forming apparatus; determining an estimated processing time and an estimated delay to print time for each of the sub-print jobs; managing the printing of each of the two or more print jobs based on the estimated processing time and the estimated delay to print time for each of the sub-print jobs by determining a printing priority for the two or more print jobs based on a printing sequence, which reduces down time of the print engine of the image forming apparatus; and printing the two or more print jobs based on the determined printing priority.

A method of managing a print job is disclosed, the method includes receiving a print job on an image forming apparatus; calculating an estimated processing time and an estimated delay to print time for each page of the print job; processing each page of the print job when the estimated processing time for a page of the print job and the estimated delay to print time for the page of the print job are equal; sending each of the processed pages of the print job to a print engine associated with the image forming apparatus for printing; and printing each of the pages of the print job on the image forming apparatus upon receipt by the print engine.

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.
