摘要： A high speed image data interface between a print server containing a page description language decomposer and an interface card, and a printer containing a rendering card and a print engine, where the interface card is physically located in the printer case and is plugged into the backplane of the printer. The interface is synchronous and carries clock, page request, line request and reset signals from the renderer, and line valid, error and data signals from the interface card. Other communications between the printer and server are carried by a telephone line or local area network. The advantage of this arrangement is that the printer manufacturer can design the printer without having to design the interface card to match the server manufacturer's requirements.

摘要： A circuit which uses a compressor to divide each separation image into 8-line strips, and to independently compress each strip, a single decompressor to decompress two or more color image separations, strip by strip, by interleaving them, and to apply them to two or more print heads, one for each color separation. DMA from a main memory is used to apply both separations to the decompressor, and the decompressor output is demultiplexed into two print heads, one for each separation. This is done to drive each color separation simultaneously in a single-pass color printer. Multiplexing logic controls the DMA into the decompressor and the output of the decompressor into separate buffers for each color separation. Additional logic uses the page and line sync from each print head to synchronize the accessing of the correct image raster from buffers at the output of the decompressor to the associated print head.
摘要翻译：一种使用压缩器将每个分离图像划分成8行条带并且独立地压缩每个条带的电路，单个解压缩器以通过交错分离来分解两个或更多个彩色图像分离，并且将其应用于两个或更多的打印头，每个颜色分离一个。来自主存储器的DMA用于将两个分离应用于解压缩器，并且解压缩器输出被解复用为两个打印头，每个分离一个。这样做可以在单程彩色打印机中同时驱动每个颜色分离。多路复用逻辑将DMA转换为解压缩器，并将解压缩器的输出转换为用于每种颜色分离的单独缓冲区。附加逻辑使用来自每个打印头的页面和行同步来将正确的图像栅格的访问同步到解压缩器的输出处的缓冲器到相关联的打印头。

摘要： A system for using the page buffer memory which stores the pixel map to generate the cursor in a CRT display. An unused portion of the memory is used to store a duplicate copy of the band in which the cursor is currently located, and the cursor is written into its appropriate location in this duplicate band, thus destroying the underlying image in the duplicate, but not in the original. The display is then generated by cycling through the page buffer except that the duplicate band containing the cursor, instead of the original band containing the underlying image, is displayed. After each display is generated, during the time when the scan returns from the bottom to the top of the display, if the cursor has moved since the previous display, the new band containing the cursor is created in the unused portion, and the display process is repeated.
摘要翻译：一种用于使用存储像素图以在CRT显示器中生成光标的页面缓冲存储器的系统。存储器的未使用部分用于存储光标当前所在的频带的重复副本，并且将光标写入其在该重复频带中的适当位置，从而破坏副本中的底层映像，但不在原本的。然后通过遍历页面缓冲区生成显示，除了显示包含光标的复制带，而不是包含底层图像的原始波段。在生成每个显示之后，在扫描从显示器的底部返回到顶部的时间期间，如果光标从上一次显示起已经移动，则在未使用部分中创建包含光标的新波段，并且显示处理重复。
