A print controller and associated methods are disclosed. Some print jobs received in the print controller are stored in a rasterized or ripped job spool. The release of these jobs is coordinated by a control system in the print controller. The control system processes an algorithm to determine a sequence of releasing one or more print jobs stored in the rasterized job spool. The control system generates a job despool token and transmits the job despool token to a rasterized job handling system through the data stream of the raw print jobs (such as through the interpreter). The job despool token follows the normal data stream of print jobs through the print controller to the rasterized job handling system. Responsive to receiving and processing the job despool token, the rasterized job handling system releases the print job from the rasterized job spool to a print queue.

Printing systems, print controllers, and associated methods of partitioning sheetside bitmaps are disclosed. A print controller in one embodiment connects to a plurality of printhead controllers that are operable to control a plurality of printhead arrays. The print controller includes an interpreter system operable to receive a print job, and to convert an image in the print job into a full sheetside bitmap comprised of an array of pixels. The print controller also includes a partitioning system operable to process the full sheetside bitmap to identify the pixels in the full sheetside bitmap designated for printing on each of the printhead arrays, and to generate a partitioned sheetside bitmap for each printhead array that contains essentially the pixels designated for printing on the printhead array. The print controller further includes an interface system operable to transmit the partitioned sheetside bitmaps to the printhead controllers associated with the printhead arrays.

Methods and apparatus herein provide for automated calibration of multiple printheads used in a multi-pass printing system. Aspects hereof print a plurality of gray scale printed patterns each printed pattern corresponding to a gray scale value for each of the multiple printheads. The printed patterns are then measured to determine the intensity (e.g., optical density) of each of the printed patterns. A measurement function is derived from the measured intensity and gray scale levels used to print each pattern. Calibrated transfer functions are then determined from the measurement function and target function where each calibrated transfer function relates, for a corresponding printhead, an input gray scale level of a pixel in an image to be printed to a calibrated gray scale level to use for the corresponding printhead when operating in multi-pass mode.

Methods, systems, and apparatus for flexible, configurable job workflow processing. Features and aspects hereof provide for generating workflow models from configurable templates. The workflow models may include one or more phases, each comprising one or more processes, each process comprising one or more steps. The Phases, processes, and steps may all be defined by configuring parameters of corresponding templates. Information defining the workflow models and all job information for jobs to be executed are entries in an integrated database such that creation and update of workflow model information and job information is performed as simple database queries and updates.

High speed printing system for printing magnetic ink systems and associated methods are disclosed. A color of the magnetic ink may be designed to resemble one of the non-magnetic inks so that instead of ejecting the one non-magnetic ink, the printing system ejects the magnetic ink. Nozzles in a printhead may also be arranged to be adjacent to each other and may be appropriately spaced without causing the inks to be mixed in the printhead. Additionally, a color transform system may be provided to transform a sheet image in accordance with ejecting at least the magnetic and the non-magnetic ink from the printhead.

Systems and methods associated with indexing of information in documents where the documents include line data with shift out/shift in (“SOSI”) code point encodings. SOSI controls are often embedded in documents encoded as simple line data (data formed to be printed on line printers). A document indexing system in accordance with features and aspects hereof converts the SOSI characters embedded in such a document to reserved codes for presentation on a user interface. The user may then precisely select trigger and field parameters used for identifying index values in such a line data document for purposes of indexing and archiving. The reserved controls help a user identify trigger and field value in a manner that the indexing system can track to determine whether and where the selected trigger and field values contain SOSI characters and thus require different column counting and indexing.

Methods, systems, and media to enhance image processing for a color reprographic system are disclosed. Embodiments of the invention may calibrate a component like scanner and/or printer in response to user input and/or coupling the component to the reprographic system. More specifically, embodiments may generate correction parameters that describe differences in color values between an image scanned by a scanner or an image printed by the printer by comparing the outputs to known characteristics like color values for the image. Some embodiments comprise a graphical user interface (GUI) to communicate with the user, allowing the user to select user preferences to change, for example, the brightness of an image being copied. Further embodiments incorporate network and phone system interfaces to communicate with remote components as well as to receive input from and/or output to other systems via email, facsimile, etc.

Systems and methods of reusing binary bitmaps for images appearing multiple times in a print job. In one embodiment, a system stores a binary bitmap for an image that appears in a print job. The system determines an offset of the binary bitmap into a sheetside, and calculates position values for the binary bitmap based on the offset of the binary bitmap. The system identifies a next appearance of the image in the print job, determines an offset of the image into a sheetside for the next appearance, and calculates position values for the next appearance of the image based on the offset of the image. The system determines if the position values for the image correspond with the position values for the binary bitmap, and verifies that the binary bitmap is reusable for the next appearance of the image if the position values correspond.

A method is disclosed. The method includes receiving a first data component of an image data stream at a cache within a control unit, appending a first signature value to the first data component to obtain a first modified image data and generating a second signature value based on the first modified image data.
摘要:
Methods, systems, and apparatus for generating and associating meta-data with a final form presentation datastream document where the meta-data is structured in accordance with the datastream component architectures. Meta-data objects (“MDOs”) are architected as components of a presentation document and thus are well defined to allow applications to reliably access and process the meta-data contained therein. The MDOs may be associated with other components of the document and are architected to be extensible and flexible while still adhering to an architectural structure. The MDOs may be descriptive (no affect in document presentation) or operational (affects document presentation if processed). Standard types of MDOs may include XML standard information, JDF standard information, PWG standard information, and digital signature information. A variety of standard categories further define typical meta-data forms and applications thereof.
