摘要： In an ink jet recording apparatus 1, a fixing signal output section 461 outputs a signal indicating that no ink drop is jetted as a mode fixing signal SP to a head driver circuit 50 for nozzle orifices 111 belonging to the group not used for recording, and a mode fixing circuit 18 of the head driver circuit 50 fixes the nozzle orifices belonging to the corresponding group to a condition of jetting no ink drops based on the mode fixing signal SP. Therefore, serial conversion and serial transfer of the data indicating that no ink is jetted (null0null data) as record data SI need not be executed for the group of jetting no ink drops, so that fruitless processing time can be eliminated.

摘要： An image processing system includes a printer engine (3) corresponding to one or both of binary and multi-value data, and a plurality of memory devices (1a, 1b) for storing bit map data and supplying a binary or multi-value video signal to the printer engine, and an interface (7) for connecting the plurality of memory devices (1a, 1b) to the engine (3). Binary or multi-value data is read out from an arbitrary memory device, two different binary data, two different multi-value data, or binary data and multi-value data are synthesized, and the synthesized data is printed. Processing, which is conventionally performed by a single memory device, can be separately performed by the plurality of memory devices, thus increasing the processing speed. Various processing operations such as binary-multi-value synthesizing processing can easily be performed.

摘要： An improved printer is provided that receives a print job from a host computer and divides the bitmap image of a page to be printed into a series of image blocks or tiles. Each image block containing non-null data will be stored in the printer's memory system, typically placed in a non-contiguous memory location with respect to other blocks. The null image data blocks will not be stored in the printer's memory system, but instead only their locations on the physical printed page will be stored in a "block list table." Each entry in the block list table contains the beginning address of the physical RAM area that contains one of the image data blocks, and also contains other variables or attributes concerning the particular image data block, such as whether or not this block is a regular non-null data block, or a "no-op" (or "NOP") block containing null data. Null data blocks require no physical memory address to be listed in their entry on the block list table, since no physical RAM areas are needed for storing null bitmap image data. Rather than building a band buffer in contiguous memory before shipping rasterized data to the laser printhead, the present invention builds in a cache a series of rasterized line segments of bitmap data in real time and sends them to the laser printhead "on the fly," by retrieving a single rasterized line segment of data, block-by-block, as needed to complete a single entire line.
摘要翻译：提供了一种改进的打印机，其从主计算机接收打印作业并将要打印的页面的位图图像划分成一系列图像块或瓦片。包含非空数据的每个图像块将被存储在打印机的存储器系统中，通常相对于其它块放置在非连续的存储器位置。空图像数据块将不会存储在打印机的存储系统中，而只是它们在物理打印页面上的位置将被存储在“块列表”中。块列表表中的每个条目包含包含图像数据块之一的物理RAM区域的起始地址，并且还包含与特定图像数据块有关的其他变量或属性，例如该块是否为常规非 -null数据块或包含空数据的“no-op”（或“NOP”）块。空数据块不需要将物理内存地址列在块列表表的条目中，因为不需要物理RAM区域来存储空位图图像数据。在将光栅化数据发送到激光打印头之前，不是在连续存储器内构建带缓冲器，而是本身在高速缓存中实时地构建位图数据的一系列光栅化线段，并将它们“即时地”发送到激光打印头。通过根据需要逐块检索单个光栅化的数据线段，以完成单个整行。

摘要： A printer having a print engine (13) and a bit map memory (12) including a number of page image areas (31) into which information to be printed is rasterized and from which information for the print engine is serialized. A digital processor (11) controlling the print engine is operable to reduce a page image area (31) to a modified page image area (37) based upon the highest and lowest addresses at which information has been written into the page image area. The digital processor (11) is also operable to begin rasterization of a new page image area when a sufficient amount of an existing page image area (41) has been serialized to make available the requisite bit map memory for the new page.

摘要： A data processing method and apparatus and printer capable of performing an HV conversion by using a single buffer. The data buffer has a length of N.times.M (=H) words and a width of N lines. First image data for H words/line is written into the data buffer for N lines. Then, the image data is read from the buffer by N pixels in a buffer widthwise direction for M words in a buffer lengthwise direction, and data for N.times.M words, is written in the area of the buffer, which has become available by the reading. These writing and reading operations are performed with respect to the entire area of the data buffer (mode A). Next, the image data is read by one pixel at M-word intervals in the buffer lengthwise direction. When data for one line has been read out, data for one line is written into the area which has become available by the reading in the buffer-lengthwise direction (mode B). Hereinafter, data input/output operation is performed by changing the mode A and the mode B.

摘要： This invention relates to a dot printer of the type in which received printing data are converted into dot-patterns to be printed. A printer of this type mainly comprises: a main memory which stores the printing data as either fixed part data and variable part data; a mechanism for identifying the fixed part data and the variable part data; and a buffer or buffers for storing the result of performing an operation, usually called "dot-expansion," on the printing data stored in the main memory. The contents of the buffers are applied to the printing head, which in turn, prints dot-images on a sheet of paper. Because the CPU dot-expands and recopies only the variable part data in the main memory into the buffer, a needless computation associated with dot-expanding fixed-part data is eliminated. In addition, if two buffers are used, a first buffer may hold dot-expanded data while the printing head is operating and while the other buffer is being filled with dot-expanded data, to be printed subsequent to the printing of the contents of the first buffer. Segmenting the main memory into fixed part data and variable part data and two-buffer scheme allow printers of the present invention to print a document faster than conventional dot-printers.
摘要翻译：本发明涉及将接收的打印数据转换为要打印的点图案的类型的点式打印机。这种打印机主要包括：将打印数据存储为固定部分数据和可变部分数据的主存储器; 用于识别固定部分数据和可变部分数据的机构; 以及用于存储在存储在主存储器中的打印数据上执行通常称为“点扩展”的操作的结果的缓冲器或缓冲器。将缓冲器的内容应用于打印头，打印头依次在一张纸上打印点图像。由于CPU点扩展并将主存储器中的可变部分数据重新构建到缓冲区中，因此消除了与点扩展固定部分数据相关联的不必要的计算。此外，如果使用两个缓冲器，则第一缓冲器可以在打印头正在操作的同时保持点扩展数据，而另一个缓冲器正在填充点扩展数据，以便在印刷内容之后打印第一缓冲区。将主存储器分割为固定部件数据和可变部件数据以及双缓冲器方案允许本发明的打印机比常规点阵打印机更快地打印文档。
