  • Patent number: 8330979
    Abstract: An information processing apparatus receives first print setting information of a document file to be printed from a printing apparatus via a network, and analyzes it. Based on the analysis result, the information processing apparatus generates divided document files by dividing the document file into data each to be output on one print sheet. The information processing apparatus generates second print setting information by rewriting the first print setting information so as to obtain the same print results of the divided document files as those of the document file before division. The information processing apparatus encrypts each generated divided document file to generate an encrypted divided document file. The information processing apparatus transmits the encrypted divided document file and second print setting information to the printing apparatus via the network.

  • Patent number: 8208162
    Abstract: The present invention relates to an image processing device that can implement printing (both printing of variable pages and non-variable pages) of an entire document and printing of only variable pages in a simplified manner. The device includes a selecting unit, a determining unit, and outputting unit. The selecting unit selects a printing mode. The determining unit determines whether the selected printing mode is an ordinary printing mode or a variable page printing mode. The outputting unit outputs printing data for a variable page and a non-variable page when the selected printing mode is determined to be the ordinary printing mode the determining unit, and outputs printing data for the variable page when the selected printing mode is determined to be the variable page printing mode by the determining unit.
