Example implementations relate to updating firmware. For example, a system according to the present disclosure may include a printing device and a computing device. The printing device may be on a network. The printing device may detect an intrusion against the printing device. The computing device may be on the network. The computing device may receive a broadcast reporting the intrusion directly from the printing device. The computing device may request, responsive to receiving the broadcast, an updated portion of a firmware code image for the computing device.

Updating firmware

Systems and methods for correcting perspective in an image are invented and disclosed. One embodiment comprises capturing image data responsive to light incident upon an image-capture device, wherein the image data includes a first perspective of a subject-of-interest, providing an image-processing algorithm executable by the image-capture device, the image-processing algorithm configured to generate modified data responsive to the image data and a perspective-correction factor, and executing the image-processing algorithm over the image data in accordance with the perspective-correction factor to generate modified data that includes a second perspective of the subject-of-interest.

Systems and methods for correcting image perspective

When a print job is canceled, the printer saves the print job for potential subsequent retrieval. The printer implements a user interface that allows a user to select from previously cancelled print jobs, and to recall such print jobs for subsequent printing.

Recalling cancelled print jobs

A method of printing including the steps of receiving a print job having image data, converting the image data into raster bits, and transmitting the raster bits to an external file storage.

Printing utilizing external storage

Methods for printing are provided. A representative method for printing includes enabling information corresponding to a print task to be evaluated, and, if it is determined that a printing device to which the print task is directed is unable to process the print task without performing a font substitution, enabling additional information to be acquired. By using the additional information, the printing device is able to process the print task without performing a font substitution. Systems and other methods also are provided.

Providing information to printing devices for facilitating printing

Documents are processed collectively by multiple printing devices. A printing device receives a request to print a document, and partitions the document into one or more blocks. The printing device communicates, to each of one or more additional printing devices, at least one of the one or more blocks. The additional printing devices convert the portions they receive to a print-ready format, and return the portions in the print-ready format to the printing device. The printing device uses the portions in print-ready format received from the additional printing devices to print the document.

Collective document processing by multiple printing devices

Embodiments of the present invention provide a modular printing system. In one embodiment, the modular printing system includes a first printer and a second printer. The modular printing system further includes a connector system adapted to interchangeably connect the first printer to the second printer and a control link adapted for communications between the first printer and the second printer to process a print job without user intervention.

Modular printing system

A printer is responsive to user input to cancel print jobs that are received after the user input. The user repeatedly selects a cancel input to indicate how many print jobs to cancel.

Variable cancel of future print jobs

Various systems, methods, and programs embodied in computer readable mediums are provided for print production cost accounting. In one embodiment, a pre-print cost of a print production of a document by an image forming device is stored in a memory. The print production of the document by the image forming device is initiated after the pre-print cost is stored in the memory. Then, a post-print cost of the print production of the document by the image forming device is generated if the print production of the document is completed. A user is charged the post-print cost if the post-print cost is available before the pre-print cost has been stored in the memory for a predefined period of time.

Secure print production cost accounting

A printer is responsive to user input to cancel print jobs that are received after the user input. For example, the user input indicates a future job cancellation period during which any print jobs will be cancelled. Alternatively, the user indicates a job cancellation count, which is a number of current or future print jobs that are to be cancelled.
