Abstract: Embodiments of the invention disclose a method for K-only (gray/black) object rendering in a high-speed color controller of a printing system. The method includes setting a flag to indicate selection of a K-only text and barcode print preference from a user of a print system, receiving one or more objects to be printed by the print system, the one or more objects including at least one of a text object and a barcode object, determining whether an input color space for the at least one text object and barcode object should be converted to K-only black ink, and rendering the at least one of the text object and the barcode object as K-only black ink if the input color space is determined to be converted to K-only black ink.

Abstract: A data structure, document data stream, method and apparatus for identifying resources prior to printing. A print data stream structure is provided that can be specified at the beginning of a document or job, or on any page boundary in a document or job, and that identifies complex resources that are required by the pages that follow. This structure is processed by a print server, which uses the resource references to download any missing resources before printing of the following pages is started. Accordingly, print underruns are avoided by ensuring that complex resources are downloaded to the printer before the first page is initiated.
