A method includes generating a machine readable code using each ink color implemented at a printer, printing the machine readable code on a first side of the medium, analyzing the machine readable code printed on the first side of the medium at a verification unit and detecting a side mismatch if the verification unit does not verify the machine readable code printed on the first side of the medium.

Printer side verification mechanism

A printer includes a print head having a first print channel to print data on each page of a print medium according to a first color plane and a second print channel to print data on each page of the print medium according to the first color plane. The printer also includes a verification unit to generate a first channel identifier to identify data printed by the first print channel and a second print channel identifier to identify data printed by the second print channel.

Print channel identification mechanism

A system, method and computer program product are disclosed. The method includes, during printing of a print data stream by a print engine, determining whether a graphical user interface has received an instruction representing an operator interrupt and, responsive to determining that the graphical user interface has received the instruction representing the operator interrupt, determining whether a command for a test print operation has been received from the graphical user interface. The method further includes, responsive to determining that the command for the test print operation has been received from the graphical user interface, performing a print of operator test samples and, responsive to determining that the command for the test print operation has been received from the graphical user interface, invoking a non-process runout function to suspend printing of the print data stream by the print engine.

Method and system for on-the-fly diagnostic print methodology

A printing system is disclosed. The printing system includes a first printer to print a first barcode on a medium including variable to be printed on the medium and a second printer to print the variable data to the medium based on the first barcode and to print a second barcode to the medium for verification that the variable data has been accurately printed to the medium.

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.

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.

Generating user defined marking settings to print marks to control post-processing devices

A printing system is disclosed. The printing system includes a first printer to print a first type of data to a medium and to print a first barcode on the medium including variable to be printed on the medium and a second printer to print the variable data to the medium based on the first barcode and to print a second barcode to the medium for verification that the variable data has been accurately printed to the medium.

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.

Notification of changed parameters in a printing system

Errors in regard to toner materials which may or may not correspond to toner materials installed in a developer unit of a print engine are avoided by providing storage of data concerning the toner in the printer rather than the dedicated processor. A feedback link is thus developed which extends from the developer unit or print engine through the dedicated processor to the supporting processors. Confidence levels in the correspondence of the information and the installed toner are increased by use of a simple switch position associated with the location of a developer unit. The feedback arrangement for avoidance of printing errors is also fully compatible with a customer changeable developer feature while allowing the printer to be operated in accordance with operating parameters specific to a special purpose toner such as MICR or a color toner.

Closed loop feedback system for alternative toners

A method and system receives a print job from a host device, parses the print job into individual print data for at least two separate printing devices, generates a random set of marks for identification of the print job, embeds the identification marks into the individual print data for a first printing device; and sends the individual print data and the marks to each printing device. Simultaneously, each printing device in the system receives its individual dataset for printing and the set of identification marks from the control unit and starts its print engine at a high speed. The first printing device prints its dataset and the identification marks on at least a first page of the printed dataset. The remaining printing devices then scan the roll of print media until they recognize the matching identification marks and begin printing their individual dataset on the roll of print media.

Method for aligning two or more independent printing systems with a single control unit and intelligent print controllers

Provided is a method, system, and program for monitoring depletion of a consumable resource in a monitored system. Information is received on at least one unit of work to be processed by the monitored system, wherein the monitored system would deplete the consumable resource when processing each unit of work. A determination is made of a rate of resource depletion per unit of work processed. An amount of resource remaining after the monitored system processes the at least one unit of work is estimated as a function of the determined rate of resource depletion and a number of one or more units of work to process. A graphical display for rendering on a computer monitor is generated indicating the estimated amount of the resource remaining.

Method, system, and program for monitoring a consumable resource used by a system

An method and apparatus for error checking. A known test pattern is written into a predetermined byte of a scan line. The method may include generating a known test pattern in a byte of a scan line and transmitting the scan line data through a first data path. The scan line data at the end of the first data path may be evaluated to determine if the test pattern is still in the predetermined byte of the scan line. If the pattern in the predetermined byte is correct, the test pattern may be removed from the predetermined byte and the scan line data may be transmitted to a print engine. If the pattern in the predetermined byte is incorrect, then a signal may be sent to terminate the transmission of the scan line data.
