Abstract: A device for printing a document, such as an HTML document, in which data to be incorporated into an output image can be described in the form of reference to an outside source, the device being capable of smooth printing a large document using a small memory. A document structural information manager creates document structural information which describes a structure of document elements, based on a result of analysis on an HTML document carried out by a document analyzer. During asynchronous downloading of substantial data of each document element, should work memory shortage occur, a memory manager unloads substantial data of a document element with a latter order at which to be incorporated into an output among those in the work memory, and saves the unloaded substantial data in an HDD. Thereafter, when data becomes no longer necessary as a result of being printed, the memory manager deletes the data from the work memory and reloads data saved in the HDD back to the work memory.

Abstract: Systems and methods for determining the authoritativeness of a document based on textual, non-topical cues. The authoritativeness of a document is determined by evaluating a set of document content features contained within each document to determine a set of document content feature values, processing the set of document content feature values through a trained document textual authority model, and determining a textual authoritativeness value and/or textual authority class for each document evaluated using the predictive models included in the trained document textual authority model. Estimates of a document's textual authoritativeness value and/or textual authority class can be used to re-rank documents previously retrieved by a search, to expand and improve document query searches, to provide a more complete and robust determination of a document's authoritativeness, and to improve the aggregation of rank-ordered lists with numerically-ordered lists.

Abstract: Overprint compositions for toner-based prints containing at least one radiation oligomer/monomer, at least one photoinitiator, and at least one surfactant are disclosed. The overprint compositions provide a number of advantages to toner-based prints, such as, for example, those subjected to abrasives, heat, and/or sunlight since the compositions protect such images from cracking, fading, and smearing. In addition, the overprint compositions provide resistance to thermal cracking, which is assessed by image analysis of the thermal crack area after exposure of the print to thermal shock.

Abstract: An electrophotographic imaging member having a charge generating layer and a charge transport layer overlayed thereon is provided. The charge transport layer has a lower surface and an upper surface, wherein the lower surface is in contiguous contact with the charge generating layer. The charge transport layer comprises a film forming polymer binder and a charge transport compound molecularly dispersed or dissolved therein to form a solid solution. The concentration of the charge transport compound in the charge transport layer decreases from the lower surface to the upper surface. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improved wear resistance, excellent imaging member electrical performance, and improved copy print out quality.
