    • An ink jet printing apparatus printing on a print medium includes a print head having a plurality of ejection ports for ejecting ink while scanning in a scan direction, and a conveyance unit including a pair of rollers for conveying the print medium in a conveyance direction crossing the scan direction by rotation of the rollers. The rollers are provided at a position at an upper stream side in the conveying direction of the print medium from a print position at which printing by the print head is performed. A detection unit is configured to detect a downstream side end of the print medium conveyed by the pair of rollers, with the detection unit arranged at a position that is a distance from the pair of rollers, in the conveyance direction, corresponding to a length of the print medium. In addition, a change unit is configured to change the ejection ports available for printing according to an error in conveyance detected by the detection unit.
    • 在打印介质上打印的喷墨打印设备包括:打印头,具有用于在扫描方向上扫描时喷射墨水的多个喷射口;以及传送单元,其包括一对辊,用于沿与所述打印介质相交的传送方向传送打印介质 通过辊的旋转扫描方向。 辊子从打印头打印的打印位置设置在打印介质的输送方向的上游侧的位置处。 检测单元被配置为检测由所述一对辊输送的所述打印介质的下游侧端部,其中所述检测单元布置在与所述一对辊的距离在输送方向上的距离处的位置,对应于所述一对辊的长度 打印介质。 此外,改变单元被配置为根据由检测单元检测到的运输中的错误来改变可用于打印的喷射端口。
