  • Patent number: 8149435
    Abstract: The present invention realizes a network printing system capable of accumulating and chasing printed data. Further, by providing a job chasing function on the printer driver side, detailed setting can be done to extract history information of the job chasing function. The detailed setting to extract history information to chase a job can be done only by a specific administrator or user so that the job can be reliably chased, whereas the administrator or user can obtain desired history information. Accordingly, a precise jog chasing system can be established.

  • Publication number: 20110279838
    Abstract: A printing control apparatus is provided which can produce an appropriate copy-forgery-inhibited pattern image by adding a monochrome copy-forgery-inhibited pattern even if monochrome mode printing is performed in the condition in which a color copy-forgery-inhibited pattern is set. When the monochrome mode printing is performed in the condition in which the color copy-forgery-inhibited pattern is set, and if the copy-forgery-inhibited pattern color is output with its color unchanged, the color is not converted into 100% black. Considering this, when a forced monochrome mode is selected, even if the user's setting for the copy-forgery-inhibited pattern is color, the color is changed to monochrome (black) before output.

  • Patent number: 8049928
    Abstract: The invention enables people to easily identify a printout image even in the case where the printout image is printed with a tint block image added thereon. More specifically, a physical page that is a printable area of printing paper is divided into areas, an intended document/image is printed in each of these divided areas (logical pages), and a tint block image is printed only in an area that is in this physical page but does not belong to any of the logical pages. Using a fact that a margin is produced in the so-called N-up printing, the tint block image is printed in this margin. Thereby, the tint block image can be printed in a location that will not interfere with whatever printout image to be printed.

  • Patent number: 7920817
    Abstract: An information processing apparatus generates printing image data of a printing image and copy-forgery-inhibited-pattern-image data of a copy-forgery-inhibited pattern image to be added to the printing image. The copy-forgery-inhibited pattern image includes a latent image and a background image. The apparatus includes a selecting unit and a printing-data generating unit. The selecting unit selects either the transparent-printing designation or overlay-printing designation, the transparent-printing designation is used for generating printing data so that the copy-forgery-inhibited pattern image is superimposed on the printing image, and the overlay-printing designation is used for generating printing data so that the printing image is superimposed on the copy-forgery-inhibited pattern image. The printing-data generating unit generates printing data based on the printing designation selected by the selecting unit.

  • Patent number: 7916339
    Abstract: This invention relates to a technique that prevents an image from falling outside a given range when a printer is controlled to form an image on an arbitrary medium while assuring a margin of a predetermined amount. A host computer shifts an image by only a partial amount of a target margin amount in a predetermined direction within an effective print range of a medium. Furthermore, the host computer controls a printer to form the image by further shifting the image by nearly the remaining amount of the target margin amount so as to form an image within the effective print range. In this way, since the host computer and printer add a margin in two steps, print data can be prevented from falling outside a given range upon processing a binding margin on the printer side.
