    摘要: A printing apparatus receives block size information of a block which is generated on the basis of the performance of a host apparatus for a print buffer for storing print data of each block and serves as a storage unit in the print buffer. Print data generated based on the performance of the host apparatus for each block corresponding to the received block size information is stored in the print buffer. The CPU in the printing apparatus controls printing by the printhead on the basis of the print data stored in the print buffer.

    摘要: An in-jet printing apparatus having a temperature detection device for outputting a signal in correspondence with a temperature, performs printing by using an ink-jet printhead which performs printing on a recording medium by discharging ink. A flag indicating whether acquisition of the temperature information is necessary or not is set, and the temperature information is obtained in accordance with the status of the flag, after the power on of the apparatus. The obtained temperature information is stored into a nonvolatile storage device. The temperature information can be obtained at appropriate timing in accordance with necessity, even if the power is interrupted during the operation. Thus a high-quality printed output can be obtained by performing a stable printing operation.

    摘要: The present invention provides an ink-jet recording method that allows a time for ink to penetrate into the recording medium and to be fixed thereto, and prevents density irregularity, color unevenness, blot between colors, and stain of the recording medium caused by contact between the recording head and the recording medium. When conducting multi-pass recording comprising the step of executing a plurality of runs of main scanning to each recording area while relatively moving the recording head which discharges ink on the recording medium, it is made possible to select a recording mode from a plurality of recording modes of different numbers of runs of main scanning, and a rest period, during which recording is discontinued after each run of main scanning, is set in response to the number of runs of main scanning corresponding to the selected recording mode.

    摘要: The present invention provides an ink jet recording apparatus capable of recording high-quality images in which not only color shading caused in the process of reciprocating recording is prevented, but also bleeding between colors inherent in a multi-pass recording method is reduced. The position of the top of ejection orifices in a second ejection orifice row for ejecting color ink is spaced a length away from a first ejection orifice row for ejecting black ink. The length is determined according to values m, n and such a condition that the value a makes (m+a) an even number. Under the circumstances, recording is performed by reciprocating scanning, which makes differences in recording time between colors equal to each other.

    摘要: It is checked whether an ink used in a printhead has a high density. The type of a printing medium used for a print operation is also identified. An image is printed by scanning the printhead once or a plurality of times. When a print operation is to be performed by using a thick ink, an image is printed by using mask data and the driving frequency of the head which are set for the thick ink. When a print operation is to be performed by using a thin ink, an image is printed by using mask data and the driving frequency of the head which are set for the thin ink and the type of printing medium used for the print operation. Codes of the respective color data of print data are determined in accordance with the types of inks used for a print operation, and an image is printed by printing a plurality of dots or dots in an overlapping state by the multi-pass method.

    摘要: Disclosed is an inkjet printing apparatus for forming an image by repeatedly causing the scanning of a printhead that prints an image in a scan area using inks of a plurality of types. Residual duty, which is obtained by quantifying the mixed state of the inks used in printing the image in the scan area, is defined. The residual duty with regard to the next scan area is found from image data, the scanning direction for printing in the next scan area is decided based upon the residual duty, and the area is printed in the scanning direction that has been decided. Thus, back-and-forth scanning and unidirectional scanning are used jointly in appropriate fashion in accordance with the printed image. As a result, high-quality printing of an image becomes possible and a higher printing speed is achieved.
