Abstract: Systems and methods are provided for printer controller, dynamic N-UP print job imaging. An enhanced printer includes features hereof to dynamically adjust parameters of a print job at any point in a print job. In one aspect hereof, the printer configures a print job for an initial set of printing parameters without host system intervention and may reconfigure those parameters during printing of the print job. In another aspect hereof, the adjustments may include adjusting the relative position of any of the N-UP images independent of any other of the N-UP images. Another aspect hereof provides that the formatting of the print job according to printing parameters by the printer occurs after rasterizing the print job into logical page images. Since the formatting is performed after rasterizing, the printing parameters may be changed at any time during printing of the print job.

Abstract: Provided are a method, system, and program generating user defined marking settings to print marks to control post-processing devices. A user interface is generated to enable user input to define at least one marking setting comprising a name of the marking setting, a dimension of a marking, and a location of the marking on the print medium. Marking settings control a printer to output markings on a print medium. The outputted markings on the print medium control at least one post processor device to perform post processing operations on the print medium. User input is received from the user interface defining at least one marking setting. The user defined at least one marking setting is stored with an existing set of marking settings to control the printer.

Abstract: Methods and systems are provided for temporarily modifying how a printer utilizing media-based scheduling handles jobs that are forced to print. In one embodiment, a print controller marks print jobs as eligible to print that have a media type corresponding to media loaded at the printer. Printing of the eligible print jobs is initiated, and a request to print an ineligible print job is received by the print controller. The print controller temporarily marks the eligible print jobs as ineligible, indicates a change to the media loaded at the printer to a media type for the requested print jobs, and initiates printing of the requested print job. Upon completion of printing, the print controller indicates a change back to the media previously loaded at the printer, and then restores the eligibility of the print jobs temporarily marked as ineligible to resume printing of the eligible print jobs.

Abstract: A print controller, methods, and software are disclosed. A print controller of the invention includes applications, a parameter manager, and a notification system. The applications register with parameter manager those parameters for which they want to be notified when a change occurs. As part of the registration, the applications designate a callback identifier (CID) for each of the parameters, where an individual CID may be associated with a single parameter or a plurality of related parameters. Responsive to receiving an indication of changes to one or more of the parameters, the notification system identifies the applications registered to be notified of changes to the parameters, and identifies the CIDs associated with the parameters that have changed. The notification system then transmits one or more notification messages, including the identified CIDs for the changed parameters, to each application that is registered.

Abstract: An apparatus, system and method for printing a print job for which the pages are orientation sensitive and includes both simplex pages and duplex pages is provided. The apparatus, system, and method includes a controller that communicates with a print module. Program code within the controller is programmed to selectively designate based on control information associated with the print job a first bin for paper to print a simplex page and a second bin for paper to print a duplex page. The first bin may be associated with a single bin indicated by the print job and is used for simplex pages while the second bin is used for duplex pages of the print job. The first bin comprises paper oriented for simplex pages and the second bin comprises paper oriented for duplex pages. The paper in the first bin and second bin may be oriented with respect to side sensitivity and/or edge sensitivity. Simplex pages are threaded along the simplex path and duplex pages are threaded along the duplex path.

Abstract: Independent asynchronous bus master devices share a common bus with control lines serially connecting each bus master in a daisy-chain contiguration. A Bus Acknowledge signal is received by a local bus master which is thereby enabled to seize control of the bus without an input synchronization delay by first inhibiting synchronization means to prevent the passage of the Bus Acknowledge signal to a downstream device for a period of time sufficient to stabilize an output signal indicating such passage. In that manner, the output signal may be used to control the immediate enabling of local bus seizure thereby avoiding local synchronization delay.

Abstract: A common memory interfacing circuit and method for coupling a memory to either a synchronous bus or an asynchronous bus. Synchronizing means are provided for synchronizing memory request signals with a local clock when the interfacing circuit is coupled to an asynchronous bus. The interface circuit responds to signals from the memory when internal memory operation has been completed and generates an acknowledge signal to send to the requesting bus. To simplify the common interface circuit, a synchronous protocol for information exchange between system components is made similar to an asynchronous protocol.

Abstract: Circuit for sequencing asynchronously the direction-indicating signal and the gating signal to bidirectional switch so that the direction-indicating signal is maintained before, during, and after the gating signal. Provision is also made for producing two gating signals in response to a change in the direction of transmission through the bidirectional switch if the direction-indicating signal changes during the gating signal.

Abstract: A peripheral processing controller controls access to a peripheral memory by specialized peripheral devices. The specialized peripheral devices process all of the data independently of a central processor that simply supervises the system. The controller uses Memory Address Registers (MARs) to control the access to the memory by the peripheral devices. Each peripheral device selects a MAR, and each MAR includes a mode register. The start address and mode are set in each MAR by the supervising central processor. Also, each peripheral device is set by the processor to select a MAR. When the controller grants each peripheral device access to the peripheral memory, the peripheral device uses whatever mode and starting address has been initialized for the MAR selected by the device. Each time the device accesses the memory, the address in the MAR is incremented so the MAR is ready for the next access. In this way, a peripheral device will advance through a block of memory space.
