  • Patent number: 7864955
    Abstract: A print system which are capable of inhibiting simultaneous use of the encrypted print and the box storage to thereby increase the security of print data. A host computer has an encryption function of encrypting print data, and issues a print job for the print data encrypted by the encryption function. A print server receives the issued print job, and has a decryption function of decrypting the encrypted print data of the received print job. A printer has a storage function of storing the print data decrypted by the decryption function, and outputs the stored print data. At least one of the host computer and the print server inhibits simultaneous use of the encryption function and the storage function.

  • Publication number: 20090284787
    Abstract: A printer according to the present invention receives a PDL via a network. Thereafter, the printer creates metadata by interpreting the received PDL and extracting rendering attribute information used in each page. The printer generates vector data from the PDL. Based on setting information on the printer, the printer generates a display list from the vector data. The generated vector data, display list and metadata are stored in a storage device in the printer in association with each other. Thus, output efficiency is improved.

  • Patent number: 7359089
    Abstract: Provided is an image processing method and apparatus in which drawing objects are collected on a group-by-group basis and rendering is switched between YMCK rendering and RGB rendering to thereby raise the image quality of a YMCK output image and mitigate a decline in processing speed. To achieve this, PDL (401) is input to an interpreter (402), which translates the PDL to drawing objects. It is then determined whether the rendering of the drawing objects is to be performed in the RGB format or YMCK format. As a result, drawing objects obtained by translation are rendered in the RGB format by an RGB renderer (407), whereby an RGB image is created, and drawing objects obtained by translation are rendered in the YMCK format by a YMCK renderer (404), whereby a YMCK image is created. The RGB image is color-converted to a YMCK image by color conversion and HT processing (409), and the YMCK image is output together with the YMCK image created by the RGB renderer (404).

  • Patent number: 7168279
    Abstract: A metal ring with smaller stress concentration is manufactured, and the manufacture and maintenance of a rolling roller for transferring a mesh-shaped unevenness to the metal ring is facilitated. A mesh-like unevenness 8 is formed to the surface of an inner circumference rolling roller 6. This unevenness 8 is formed by rotating the inner circumference rolling roller 6 at a predetermined speed, and moving a grinder 9 back and forth in the axial direction of the inner circumference rolling roller 6 while biasing the grinder toward the surface of the roller 6 with predetermined force. The grain size of the grinder is between #270 and #1000. When the inner circumferential surface of the metal ring 1 is rolled using the inner circumference rolling roller 6, a mesh-like unevenness 2 is transferred onto the metal ring 1.
