Abstract: System, including method and apparatus, for controlling printing device outputs by selectively fulfilling or denying corresponding output requests based on the class of each output request. The class may be determined by the type of each request and/or the specific input port through which each request is received.

Abstract: A fabric made from yarns that, when woven, mimic straw or other dried grass fabrics. The fabric has a set of polyolefin slit film warp yarns and at least two sets of polyolefin slit film weft yarns interlocking with the set of slit film warp yarns in the form of a weave. At least one of the sets of slit film warp yarns or slit film weft yarns being fibrillated to form ridges in the woven yarns that create a fabric that has a texture of a dried grass fabric having a substantially smooth face. Further, the sets of slit film weft yarns may be woven with the set of slit film warp yarns, so that the fabric has a variability due to varying light reflectivity, coloring and exposure of the sets of slit film warp yarns and slit film weft yarns within the fabric that creates an overall appearance that is a manifestation of a dried grass fabric.

Abstract: A printing device stores data associated with a print job in a memory device. The print job or portions of the print job have an associated reference count(s) indicative of whether the print job or portions of the print job are write-protected. The reference count(s) is incremented and/or decremented responsive to printing of the print job. A control system is configured to permit the print job or portions of the print job to be overwritten with new data when the reference count(s) reach a particular value indicating to the control system that the print job or portions of the print job are no longer write-protected. As a result, memory capacity for print jobs (up to twice the memory capacity of conventional printing devices) and print speed performance improvements are realized over conventional printing devices.

Abstract: A system and method dynamically allocate memory to a RAM disk. Upon a file transfer to the RAM disk, a device driver determines an amount of memory required by the RAM disk then requests the required amount of memory from a memory manager. As files are deleted from the RAM disk, the memory is released from the RAM disk by informing the memory manager of the addresses of the memory to be released. Sector freelists tracks each cluster of memory allocated to the RAM disk. When a sector becomes inactive, a corresponding bit in a sector freelist indicates the inactive status of the sector. When all of the sectors in a cluster are inactive, the cluster is released for the RAM disk.

Abstract: Apparatus for writing compressed data to a storage device having multiple storage areas. The apparatus identifies one or more storage areas to receive the compressed data based upon the compression ratio of the compressed data and the characteristic transfer rates of the storage areas. The apparatus then writes the compressed data to the Identified storage areas. This is accomplished so that when the compressed data is later read, the storage device has at least a minimum output rate. The storage device may, for example, be a disk storage unit for a laser printer. The compressed data may be compressed video data describing a document to be printed.
