    Abstract: A printing system for producing prints, with each print including an image represented by image data, is provided. The printing system includes a memory for storing and buffering the image data of a selected print and an image output terminal, communicating with the memory, for printing the image of the selected print on a substrate. The printing system further includes marking software, operatively associated with the image output terminal, for determining a value for the maximum amount of memory to be used in printing selected ones of the prints, and a resource manager, communicating with the marking software and the memory, for managing the memory. In practice, the resource manager receives the value from the marking software and the substrate is fed to the image output terminal when the resource manager determines that the value corresponds with a selected amount of available memory space and that an additional predetermined condition is satisfied.

    Abstract: A method for scheduling transfers in a printing machine (Fig. 2) of the type having a scheduler (162;Fig. 9) communicating with both a first disk (Disk 0) and a second disk (Disk 1), the first and second disks having a combined bandwidth. The method for scheduling comprises the following steps: First, a first transfer (CurrentOp1) to be performed on a first location of the first disk (Disk 0) during a first time interval (tSX1-tDX1) and a second transfer (NextOp 1) to be performed on a second location of the first disk (Disk 0) during a second time interval (tSX2-tDX2) are both scheduled, with the scheduler (162), so that a first time gap interval (tGAPx) exists between the first time interval (tSX1-tDX1) and the second time interval (tSX2-tDX2 ). Second, a third transfer (CurrentOp2) to be performed on a first location of the second disk (Disk 1) during a third time interval (tSY1-tDY1) and a fourth transfer (NextOp2) to be performed on a second location of the second disk (Disk 1) during a fourth time interval (tSY2-tDY2) are both scheduled, with the scheduler (162), so that a second time gap interval (tGAPy) exists between the third time interval (tSY1-tDY1) and the fourth time interval (tSY2-tDY2). Finally, a fifth transfer (InsertOp) to be performed during a fifth interval (tSI-tDI) is scheduled, with the scheduler (162), so that the fifth interval (tSI-tDI) occurs during either the first time gap interval (tGAPx) or the second time gap interval (tGAPy) in a manner that maximizes the combined bandwidth of the first (Disk 0) and second (Disk 1) disk.
