摘要： A conversion program selectively decomposes viewable files, such as PDF files, and generates a print-structured, bi-directional stream composed of print data objects, resource objects and command objects. The conversion program uses a mapping table to determine which resources have already been sent to the printer so that redundant resources are not re-sent to the printer. The resources and page data for each page are assembled in order and sent to the printer so that the resources necessary to render a page precede the page data. In this manner the printer always has the resources necessary to print each page. The print data, resource and command objects are sent from a print server which controls the print system to a printer by means of a containerized data stream which is bi-directional. A reply object is used to provide information concerning processing of the data from the print server to the printer.
