摘要:
In a print system comprising a computer and a printer connected to the computer, a logical printer driver makes print instructions of a prepared document, prepares a PDL document and print information from the document, and spools as a print job, a spool control section transfers the spooled print job to a PDL processing section, which then processes the PDL document in accordance with the print information and transfers the PDL document to an interpreter, which then interprets the PDL document, expands the PDL document into a dot image, and stores the dot image in an output work, and an output control section sends the dot image to a print engine for printing the document in the specified format from the computer.
摘要:
In a print system comprising a computer and a printer connected directly or indirectly via a network to the computer, the printer stores documents prepared by the computer, has a page/document layout processing section for the stored documents, and can output document data undergoing page/document layout, provided by the page/document layout processing section.
摘要:
A packet switch apparatus including a plurality of connecting points, each being coupled to one of a plurality of data processing units, and apparatus for receiving a first packet including identification information of a first data processing unit via a first connecting point. The invention further includes a storage for storing correspondence between the first data processing unit and the first connecting point based on the identification information. Apparatus, responsive to reception of a second packet from a second data processing unit to be transmitted to the first data processing unit, transmits the second packet to the first data processing unit via the first connecting point based on the correspondence stored in the storage.
摘要:
In a print control apparatus, even when an error such as a paper jam or the like which needs the reprint occurs in a printer, in order to perform an error recovery to generate the accurate reprint result, for preparation of the error recovery, a command buffer preserving section to preserve commands and drawing attribute parameters of each page head (or a command file preserving section or a page buffer preserving section to preserve a drawing dot image) and a preservation command buffer use redrawing/reprint preparing section to perform the error recovery by using the preserved contents (or a preservation command file use redrawing/reprint preparing section or a preservation page buffer reprinting section) are provided in the print control apparatus. When the error which needs the reprint occurs, even for a command of the type such that the drawing attribute parameters are handed over between pages, the accurate reprint is executed by using the preserved contents.
摘要:
A printing apparatus executes a series of print commands from a host computer and controls a printer engine equipped with a rotation-type double-side printing mechanism. The printing apparatus comprises page buffers, a drawing-processing unit for drawing data on the page buffers. and a printing-processing unit for processing printing of a drawn data. The printing-processing unit determines whether the drawn data to be printed is first or second-half page is to be performed, and immediately starts printing of first-half if first-half page is determined or puts printing of the second-half page in a wait state if second-half page is determined. The printing-processing unit releases the printing of the second-half page from the wait state when a predetermined condition has been detected. The predetermined condition can be that the number of sheets retained in the printing mechanism has reached a predetermined maximum number or that a final page of a document has been detected by receiving a command indicating the end of a double side printing. The predetermined condition can also be that a change of sheet-sizes, a change of paper supply units or a change of paper-eject units has been detected.
摘要:
A printing system includes a network, a first computer connected to the network, a second computer connected to the network, and a printer connected to the network. The first computer instructs the printer to print. The printer includes a printer controller and a printer engine. The printer controller includes an individual printer management part for managing the printer, and an individual printer information DB part. The second computer includes a total printer management service processing part for managing a plurality of printers including the printer connected to the network, and a total printer management information DB part. The second computer communicates with the printer controller and/or the first computer over the network to manage the printer to cope with trouble in the printer, order consumable items and replacement parts for the printer, and update programs and data for using the printer.

摘要:
Drawing processes and print processes for respective pages are performed in accordance with print commands by a plurality of processors. The print commands over the plurality of pages are stored in a command buffer. While successively allotting the drawing processes for different pages to different processors, a chain of the print commands ranging over the plurality of pages is fetched from the command buffer, and imaginary drawing operations for setting drawing attribute parameters of respective pages are executed sequentially without executing real drawing operation for printing actual drawings. The real drawing operations are executed for pages having completed the imaginary drawing operations by the allotted based in parallel on the print command chain and in accordance with the drawing attribute parameters set during in the imaginary operations.
