    • Nozzles for ejecting color ink are aligned in the conveying direction of a recording sheet at a pitch corresponding to three times the pitch of nozzles ejecting black ink. A region in which an image is printed is divided into sixteen regions segmented into four parts in the scanning and conveying directions. Each region includes eight dots in the scanning direction and four dots in the conveying direction. With respect to regions which include one character, in one side attachment regions, black ink is ejected only when an ink jet head is moved to the right side. With respect to regions which include one character, in the other side attachment regions, black ink is ejected only when the ink jet head is moved to the left side.
    • 用于喷射彩色墨水的喷嘴以对应于喷射黑色墨水的喷嘴的间距的三倍的间距在记录片材的传送方向上对齐。 其中打印图像的区域被划分成在扫描和传送方向上分成四部分的十六个区域。 每个区域在扫描方向上包括八个点,在输送方向上包括四个点。 对于包括一个字符的区域,在一侧附接区域中,仅当喷墨头向右侧移动时才喷射黑色墨水。 对于包括一个字符的区域,在另一侧附接区域中,仅当喷墨头向左侧移动时才喷射黑色墨水。
