Abstract: 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.

Abstract: 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.

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: 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.

Abstract: 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.
