    • This invention re-encodes encoded data (e.g., PackBits encoded data), which is expressed by a data format of a runlength code part indicating the runlength of the same data and a data part indicating the data, and a runlength code part indicating the runlength of a different data stream and a data part indicating the different data stream, to the same data format without decoding that encoded data, thereby improving a compression ratio. To this end, upon reception of data encoded by a PackBits encoding process, a data division unit separates that data into information indicating the runlength of data, and a data part, and outputs them as num and data. A data processing unit masks a predetermined bit in accordance with an instruction from a monitor unit, and outputs that result to a data combining unit. The data combining unit and a data output unit reconstruct and output data in the PackBits format in accordance with the masked data part and num data.
    • 本发明对由指示相同数据的游程长度的游程长度代码部分的数据格式和指示数据的数据部分表示的编码数据(例如,PackBits编码数据)进行重新编码,以及指示运行长度的游程长度代码部分 的不同数据流和指示不同数据流的数据部分转换成相同的数据格式,而不对该编码数据进行解码,从而提高压缩比。 为此,当接收到由PackBits编码处理编码的数据时,数据分割单元将该数据分离成指示数据的行程长度的信息和数据部分,并将其输出为num和数据。 数据处理单元根据来自监视单元的指令对预定位进行掩蔽,并将结果输出到数据组合单元。 数据组合单元和数据输出单元根据掩蔽的数据部分和num数据重建并输出PackBits格式的数据。

    • A print processing apparatus processes a print job that includes print data corresponding to a plurality of pages and first paper information relating to papers used in printing of the print data. The microprocessor unit sets second paper information relating to a paper stacking order of a paper stack including a plurality of types of papers placed in a mixed state in one paper feeding tray. Then, the microprocessor unit compares the first paper information with the second paper information. The microprocessor unit controls the printer based on an obtained comparison result so that the print data can be printed on a target paper on which the print data should be printed, and controls the printer based on the obtained comparison result so that any surplus paper other than papers that are necessary and sufficient can be separated from papers on which the print data has been printed.
    • 打印处理装置处理包括对应于多页的打印数据的打印作业和与打印数据的打印中使用的纸张有关的第一纸张信息。 微处理器单元将包括在一个供纸托盘中以混合状态放置的多种类型的纸张的纸叠的纸堆叠顺序相关的第二纸信息。 然后,微处理器单元将第一纸信息与第二纸信息进行比较。 微处理器单元基于获得的比较结果来控制打印机,使得打印数据可以打印在要打印数据的目标纸张上,并且基于获得的比较结果控制打印机,使得除了 必要和足够的纸张可以与打印数据打印的纸张分开。
