Abstract: A printing system includes a printer and computers connected by an network. A mail server is provided for transmitting notification data from the printer to the computers in the form of an email message. Print data stored in the printer is erased once the print data has been used for reprint operations a certain amount of times. If the amount of print data stored in the printer exceeds a reference size, then print data sets are selected for erasure based on predetermined conditions. Data stored in the printer can be retrieved from the printer and amended at the computer.

Abstract: A laminated ink distribution structure for a printhead has a number of layers adhered to one another with each layer including a number of ink holes formed therethrough. Each ink hole has communicating therewith a channel formed in one side of the layer and allowing passage of ink to a transversely located position upon the layer, the transversely located position aligning with a slot formed through an adjacent layer of the laminate. The laminated ink distribution structure is fixed to a distribution housing via which different inks are conveyed from an ink cassette. The laminated structure distributes the different inks to an array of print chips of a color printer.

Abstract: A method of processing page description data for printing on a printing device having a print engine for printing on an output media. The method includes receiving page description data comprising objects to be placed on the output media where each object has a position on the output media. An area to be printed on the output media is divided into a first and subsequent bands. The objects are interpreted one object at a time to produce display list data. When all objects that intersect the first band have been interpreted, display list data for the first band is rendered without regard to whether objects or portions of objects in subsequent bands have been interpreted.

Printing information including control codes is inputted from an external instrument into a memory device and is stored therein. The control codes are detected from the printing information stored in the memory device. It is judged with which one of the control code systems the detected control codes are compatible, to select one of the operation modes corresponding to the control code system judged to be compatible.

Abstract: A method and apparatus are described for the electronic delivery of a document, originated at a local site by a source which has a printer output that normally is connected to a printer, to one or more remote locations having printers or display devices which may differ from the printer normally connected to the printer output of the document generating source. Printer command signals which normally are provided at the printer output are converted to character and position data which represent the respective characters and their horizontal and vertical positions on each page of the document. The character and position data are transmitted to a remote location, either directly or via a distribution unit which transmits a document to one or more remote locations, whereat the data is reconverted to a form for driving a printer or other display device, resulting in a line-for-line conforming copy of the original.

Abstract: A computerized system for the rapid rendering of written or spoken material into printed text. A stenographic record of the material is produced by a reporter according to a stenographic system including "automatics" to enable batch translation of the stenographic data. The record thereby produced is translated rapidly and with a high degree of accuracy by a computer having a dictionary of the system stored in its memory. The translation is displayed upon the screen of an editing device for rapid editing by a word processing operator. The edited translation is applied to a transmitting modem. The modem encodes the edited translation for transmission to a remote computerized typesetter. The typesetter is directly programmed with the edited translation to produce a printed text of the material.

Abstract: An interface for converting standard computer character code, in either serial or parallel form, into a sequence of simulated acoustic wave pattern signals. These wave pattern signals are then applied to an acoustic bar operated typewriter, like the typewriter sold under the mark "Typetronic" by the SCM Corporation, duplicating the acoustic wave fronts that are generated by the keyboard. Thus the typewriter is conformed to operate as a data processing printer without any reduction in the functions thereof.
