Method and apparatus for printing documents including embedded print objects

摘要

An intelligent printing system is extended to handle print objects such as EPS and PDF print objects without requiring the objects to be reformatted by selectively decomposing the EPS and PDF print objects and placing resource information contained in the objects in a resource database along with the print data. The resource information is not duplicated; only the first appearance of a resource is stored, later duplicates are discarded. Appropriate references are placed in the page description data stream so that the resource information can be retrieved and downloaded to the printer when the data is being processed at the print server. The downloading of a particular resource occurs only once. When the print data is sent to the printer, the downloaded resource information is recombined with the data and the combination is sent to a conventional EPS or PDF rasterizing program which converts the objects to printable data.
