  • Patent number: 6538764
    Abstract: Print data including text or graphics data is transferred from a host computer to a printer. The printer develops the received data on a band basis. When data processing to be performed by the printer is expected to fail due to shortage of the memory area size, the host computer cancels the data which has already been sent to the printer, and develops the text or graphics data to form image data. The image data thus formed is sent to the printer. Image data is transferred in a hierarchical manner. Disclosed also is a method which makes it possible to eliminate as much as possible any data processing failure in the printer attributable to shortage of memory capacity.

    Abstract: An imaging device and method enable the freeing of memory during a punt (print overrun) avoidance operation and during a duplexing operation for enhanced page throughput. Specifically, if a first race condition threshold is met, being indicative of an estimated need to pre-rasterize a band from a page of image data for punt avoidance, and if after pre-rasterization it is determined pre-rasterization is not actually needed for punt avoidance, then the pre-rasterized band is evaluated relative to its display list for memory savings purposes for improved page throughput performance. Similarly, if a duplex condition threshold is met, being indicative of a band being part of a first side of a duplex page being processed and of an estimated need to save memory for processing of the second side of the duplex page, then the band is pre-rasterized and evaluated relative to its display list for memory savings purposes for improved duplex page throughput performance.

  • Patent number: 6463512
    Abstract: The present invention aims at restoring backup data in a predetermined order and avoiding damage from being given to the system even when the backup data are destroyed. Flags Ferr and Feeprom and a variable i stored in a DRAM are initialized (S1 to S3). When the variable i is smaller than the number n of EEPROMs (hereinafter referred to as “PROM(s)”), the ID code of a PROM in question is read and loaded into the DRAM (S4 to S6). When the variable i equals the number n, the variable i is cleared (S7). Then, a variable j is initialized (S9), and it is determined whether or not each PROM ID stored in the DRAM matches with a mask ROM ID until the variable j becomes greater than the number n of PROMs (S11). If the answer is “No”, the variable j is incremented (S13), while if “Yes,” a number corresponding to the variable j then assumed is loaded into the DRAM as the flag Feeprom (S14).

  • Patent number: 6441917
    Abstract: In a printing apparatus which performs printing operation in an emulation mode designated by a host computer, data necessary for the designated emulation mode is down-loaded. First, a fixed data buffer size is reserved in accordance with the emulation mode which requires the maximum amount of data to be down-loaded. Then, a ring buffer for receiving data is assigned next to the fixed data buffer. After the data size to be down loaded is determined, portions of area reserved for the fixed data buffer which becomes unnecessary is reassigned as print data buffer. Since the print data buffer is a ring buffer, if no received data is stored at an address which is at the border between the fixed data buffer and the print data buffer, it is possible to move the border. Therefore, the printing apparatus waits until a state of the print data buffer changes to a state in which no received data is stored at the address at the border, then expands the print data ring buffer.

    Abstract: Using the concept of off-screen rendering, a Unicode encoding value for a non-Latin1 glyph is converted into a bitmap image using Java™ in order to print glyphs that are not supported by a printer. The method uses the JDK application information together with the platform specific operating system's information to perform a non-operating system specific rendering or generic rendering of the non-Latin1 Unicode glyphs for use in printing the glyphs. This solution is glyph-based instead of font-based and works within the confines of Java™ classes and methods. It is primarily an extension of the Java language that exposes a host font manager, such as a TrueType™ font engine, in such a way as to bring the bitmap of a glyph into an application or applet executing on the virtual machine. The bitmap of the glyph may then be printed.

  • Publication number: 20020093669
    Abstract: An imaging device and method provide a binding of complexity indicia to bands of a page being composed for video imaging. The indicia enable memory management tasks to be performed on the bands while the page is waiting in the page pipe to be imaged. Advantageously, the memory management tasks are performed without waiting for any already composed page to finish imaging. Accordingly, page throughput of a multi-page print job is improved. In one embodiment, the indicia includes at least one data element that is indicative of the band being safe for being acted upon by the memory management tasks. In an alternate embodiment, the indicia includes a data element that is indicative of a complexity of the band for being video imaged, and a further data element that is indicative of an incremental complexity of the band relative to a given memory management task that may be performed.

  • Patent number: 6421137
    Abstract: In an image forming apparatus in which a photosensitive drum has the form of a cartridge, a non-volatile memory is provided on the cartridge and a cumulative number of times image forming has been performed is stored in the non-volatile memory, a write-in-progress flag is set in the memory before a data set is written to the memory of the cartridge, and the write-in-progress flag is reset after writing of a data set to the memory ends. A plurality of identical data sets are written to the memory. If, when data sets are read out of the memory, there is a data set for which the write-in-progress flag is still in the set state, it is judged that the write operation for this data set ended in mid-course and, hence, the content of this data set is rewritten to the content of another valid data set.

  • Publication number: 20020085230
    Abstract: A method and system for easily storing logo data in a target printer. A data storage file for storing the logo data in the target printer is produced by creating the print data, generating a set of commands for storing the print data in the non-volatile storage of the target printer, compiling the data storage file containing the print data and command data set, and outputting the data storage file. When a host terminal accesses this data storage file, it runs the commands in the detected command data set, thereby sending a storage command data set to the target printer. The target printer then runs the storage commands and locally stores the logo data.

  • Patent number: 6384930
    Abstract: A printer-control-only hardware circuit (control circuit) is interposed between a printer driver of a host computer and a printer. The printer driver transmits to the control circuit a series of control circuit commands for use with the control circuit. The series of control circuit commands include several types of commands, such as a backend parameter setting command used for sending a backend parameter which is required for resetting the printer and an RGB data transmission command for the purpose of transmitting full-color RGB raster data. The control circuit identifies the types of control circuit command received. If the control circuit command is a backend parameter setting command, the backend parameter is stored in the command buffer within a memory device.

  • Patent number: 6384931
    Abstract: The invention is a method and system of capturing a destination address from a label print stream in a data processing system which is capable of supporting an object oriented programming environment. The method begins with the initiation of a print stream from a label application. A virtual driver is selected as the intended destination device of the print stream. The virtual driver directs the print stream to a print intercept automation server (PIAS). The PIAS causes the system to display on a monitor a print field selection. The system operator selects an envelope print field from the print intercept automation server. The envelope print field is a set of objects established in the object oriented environment and comprises a mailpiece OCX and an indicia printing control object. The print stream is then parsed to extract a set of address data defining a destination address from the print stream by the print automation server.
