  • Patent number: 9978005
    Abstract: A printer includes a receiving unit configured to receive data for drawing a character at a predetermined drawing position, and a drawing unit configured to, based on the data for drawing the character, draw the character multiple times by varying a drawing position of the character each time. The drawing performed multiple times includes at least drawing at the predetermined drawing position, drawing at a drawing position shifted from the predetermined drawing position only in a horizontal direction, and drawing at a drawing position shifted from the predetermined drawing position only in a vertical direction.
    Type: Grant

  • Patent number: 9075356
    Abstract: In an image forming apparatus having a fixing unit for fixing a toner image on a printing medium, it is necessary to control a fixing temperature with high precision according to the content of an image. An image forming apparatus of the present invention includes: an input unit configured to input image data; and a controlling unit configured to control the fixing temperature of the fixing unit based on a size of a continuous region of pixels whose pixel values are equal to or larger than a predetermined pixel value in the image data.

  • Patent number: 9014586
    Abstract: An image processing apparatus controls a fixing temperature of a fixing device which fixes an image to be formed. The apparatus obtains an attribute of each page included in a print job including a plurality of pages. Then, the apparatus controls a fixing temperature for each page, based on a change of the obtained attribute by the obtaining unit between continuous pages. In a case where there is a change of a printing mode between the continuous pages, the apparatus sets a fixing temperature of a preceding page according to the change close to a fixing temperature of a following page.

  • Patent number: 8873109
    Abstract: A printing apparatus for combining a document image with a copy-forgery-inhibited pattern image to perform printing includes a unit configured to determine a video count value from the document image, a unit configured to determine a video count value from the copy-forgery-inhibited pattern image, and a unit configured to multiply the video count value determined from the document image by a rate of dots other than dots constituting the copy-forgery-inhibited pattern image in the document image to obtain a product, and to add, to the product, the video count value determined from the copy-forgery-inhibited pattern image to determine a video count value for the printing.

  • Publication number: 20140092442
    Abstract: Conventionally in a case of storing image data in an HDD, JPEG compression is executed to the image data for reducing the data size thereof and then the image data is stored. However, there are some cases where when the JPEG compression is executed to the image data including the copy-forgery-inhibited pattern and the like, degradation in image quality occurs. In regard to the image data including the copy-forgery-inhibited pattern and the like, the halftone processing is executed by the halftone processing unit without irreversible compression. Therefore, the image data can be stored in the HDD and like in a state of being small in a data size and with the image degradation restricted.
