摘要： A compressor can compress an image by reducing the amount of data while preserving the information. Some compressors use run length coding wherein image data is converted into a series of run length code words. The efficiency of run length coding can be increased with the introduction of differential run length code words. The differential run length code words can augment the original set of run length codes. Differential run length codes vary from current run length codes by encoding runs of differences.

摘要： Shifting a page image while it is still in compressed form. The page image is compressed into independent strips that are a full page in the fast scan direction, and a small number of scanlines in the slow scan direction. Then, to shift the page image, whole strips can be deleted in one margin and/or deleted from the other. If the number of scanlines per strip is small enough, the difference in a margin created by the change of one strip will not be apparent. This invention can be used to advantage when it is decided at print time that the output shall be in the form of a saddle-stitched booklet requiring two-up printing, folding and subsequent trimming of the outside edges to uniform alignment. Here, a progressive page shift can be introduced at the printer controller while the images are still compressed, instead of requiring the change to be done to the PostScript Master, which would require reRIPing or decompression, shift and recompression.
摘要翻译：在仍然处于压缩形式的同时移动页面图像。页面图像被压缩成快速扫描方向上的整页，并且在慢扫描方向上的少数扫描线的独立条带。然后，要移动页面图像，可以在一个边距中删除整个条带和/或从另一个边缘删除。如果每个条带的扫描线数量足够小，则通过一个条带的更改创建的边距的差异将不明显。当在打印时确定输出应为需要双向打印，折叠和随后修剪外部边缘以均匀对准的马鞍缝合小册子的形式时，可以使用本发明。这里，可以在打印机控制器上引入逐行页面移位，同时图像仍然被压缩，而不需要对PostScript Master进行改变，这将需要reRIPing或解压缩，移位和重新压缩。

摘要： A method of improving the compression ratio of image data in the form of foreground data printed over background data by arranging both kinds of data pixels into 8 by 8 pixel blocks. All blocks that do not contain at least one pixel to be printed are deleted before compression. The deleted blocks will be entirely background pixels that will be overlaid by foreground pixels, or entirely foreground pixels that will not be printed because they are located outside of foreground masks.
摘要翻译：通过将两种数据像素排列成8×8像素块来提高以背景数据打印的前景数据形式的图像数据的压缩比的方法。所有不包含至少一个要打印的像素的块在压缩之前被删除。被删除的块将是完全背景像素，将被前景像素覆盖，或完全是由于它们位于前景掩码之外而不会被打印的前景像素。

摘要： A run length codeword system which has a set of codewords, each codeword being one byte. The first codeword of a run is divided into a 4-bit code part and 4 bits of printing hints. The code part specifies the source of the data, and the format of the remaining bytes in the run. The remaining one or two codewords specify the number of remaining data bytes in the run, or color values.

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： A circuit for performing high-speed 90 and 270 degree rotations of an uncompressed image in a page buffer. The rotation is performed as the data is written into and read from the page buffer, thus requiring no additional time. A special memory mapping technique is used to make efficient use of the page buffer memory.
