摘要： This invention reduces an unprinted stripe occurred by edge deviation of a printhead. An inkjet printing apparatus according to this invention can execute a first printing mode in which an image is printed by scanning the printhead in a first region on the printing medium N times and scanning the printhead in a second region adjacent to the first region (N+1) times, and a second mode in which an image is printed by scanning the printhead in the first region M times and scanning the printhead in the second region (M+1) times. The width, in the conveyance direction of the printing medium, of the second region printed in the second printing mode is narrower than the width, in the conveyance direction of the printing medium, of the second region printed in the first printing mode.

摘要： There are provided a printing apparatus and printing method capable of achieving high-quality printing by fine ink droplets, and collecting unwanted ink droplets. According to the method, ink droplets discharged from a printhead are negatively charged by the negative ions in printing. A printing medium is charged positively opposite to the polarity of ink droplets. By the electrostatic force, discharged ink droplets travel toward the printing medium, and the amount of ink droplets attached to the printing medium is increased. In addition, an ink mist collecting unit having a positive electrode is employed to collect floating ink mist.

摘要： Disclosed is a printing control system in which a host computer and a printer are connected so as to be capable of bidirectional communication. The printer stores color-conversion information, which is model-specific information, and a control command in a ROM and, in response to a command from the host computer, transmits the stored color-conversion information to the host computer. Using the color-conversion information and control command, the host computer sets the parameters of a printer driver, creates a command and transmits generated print data to the printer.
