摘要： An exemplary scalable print spooler efficiently prints data on a printer and is most effective in use with a dedicated print server. One use of the invention is with a print server that services a large number of client computers having applications programs having a need to print data. These could include, but are not limited to, word processing applications programs. A server computer has software that implements a server print spooler for coordinating the printing of data sent to the print server by the client computers. A number of printers are coupled to the server computer for printing under direction of the server print spooler. Client calls to the print spooler are accomplished by asynchronous procedures that communicate by means of an remote procedure call channel. A thread pool at the print server services these calls without unreasonable context switching between client requests.

摘要： Spooling strategies are described for producing job information that conforms to a hierarchical structure, and then storing the job information in a spool storage. The job information is then retrieved from the spool storage and consumed. The structured job information includes a multi-level hierarchy of nodes, including a job level that represents the entire job, a document level that represents a document to be processed within the job; a rendition level that represents a rendition of the document to be processed; and a page level that represents a page associated with the rendition. The hierarchical structure can also include resource nodes and metadata nodes associated with any level of the hierarchy, respectively representing resources and metadata. The hierarchy can optionally be composed using one or more selection and sequence parts. Program logic implements the production and consumption of the job information by providing a collection of logic modules for selectively adding and retrieving elements to the hierarchically structure. The program logic also provides logic for enumerating the contents of the job information and for signaling the occurrence of various events associated with the processing of the job information.

摘要： Notification mechanisms for use in connection with print systems are described. In one embodiment, a notification mechanism extends from a printing application to the spooler, from the spooler to a hosting process, and back to the spooler. The notification mechanism can allow interested applications, such as print user interfaces, to register to receive updates on the progress of a print job. The notification mechanism provides a very rich and robust mechanism through which notifications can be generated and received.

摘要： A flexible printing subsystem is enabled with a printer filter pipeline. A configurable and arbitrary number of printer filters forming a printer filter pipeline are applied to files that are to be printed. In a described implementation, the printer filter pipeline may implement enhancement features and conversion functions as determined by the individual printer filters forming the printer filter pipeline. The printer filter pipeline is established in accordance with a printer filter configuration file. The printer filter configuration file stipulates a printer filter order and includes a printer filter entry associated with each printer filter to be part of the printer filter pipeline. Each printer filter entry identifies the associated printer filter by name and enumerates the interfaces thereof. Printer filters may be adjacently linked in a printer filter pipeline when their mating interfaces match.
