摘要:
A printer provided with a printer controller and a printer engine, wherein the printer controller includes a user interface control unit with a function for grouping together parameters associated with the paper, overlay and so on and recording this group of parameters under a desired name.

A printer system includes a plurality of printing mechanisms, a paper inversion mechanism that inverts a paper between the printing mechanisms, a paper buffer that adjusts a time lag in a synchronous operation, and a controller that receives print data from a host computer and synchronously operates the printing mechanisms to perform double-strike or double-sided printing. Preferably, the controller includes a unit that measures a length of a paper path extended between the printing mechanisms and enters a setup value to perform error recovery printing, an image buffer that stores an amount of data equivalent to a distance between an image transfer point and a fixing point, a pointer function that indicates locations of image data and of data in the image buffer, and a function that employs the pointer function to calculate a range and performs error recovery printing, when a malfunction has occurred and a paper is re-loaded.

As a user selects one of error recovery methods for each error category, and the selected method is stored in a memory. When an error occurs, an error recovery method corresponding to an error category of the error is detected. If the detected method is automatic print continuation, then the error is ignored and print operation is automatically continued. If the detected method is a recovery by user's operation, then an error message is displayed, and a procedure is performed in accordance with an instruction from the user.

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:
A printing method for use with a print system including a computer and a printer connected to the computer directly or by way of a network, the method including the steps of: directing the printer to effect printing and storage of a document prepared by the computer in an arbitrary combination of formats; transmitting the document to the printer; effecting receipt by the printer of the document transmitted from the computer; and effecting printing and storage of the document according to the instruction from the computer.
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.
