    • This invention provides a printing apparatus which employs a print head constructed to minimize a memory area to hold ejection data and not requiring a sophisticated manufacturing technology and thus realizes a print mode to perform a higher-than-normal-resolution printing, making it possible to form a high quality image when needed. For each of cyan and magenta that make large contributions to the formation of an image, four nozzle arrays are allocated. For each of the remaining colors, two nozzle arrays are allocated. For cyan and magenta, the interval between adjoining nozzles of the paired two arrays is set to ¼ the nozzle pitch. For cyan and magenta, all of the four nozzle arrays are used in the high resolution print mode and, in the normal print mode, only two of the four nozzle arrays are used for printing. Of the paired adjoining nozzle arrays, only one is used.
    • 本发明提供了一种打印装置,其采用构造成使存储区域最小化以保持喷射数据并且不需要复杂制造技术的打印头,从而实现打印模式以执行高于正常分辨率的打印,使得可以 在需要时形成高质量的图像。 对于对形成图像做出巨大贡献的青色和品红色中的每一个,分配四个喷嘴阵列。 对于每个剩余的颜色,分配两个喷嘴阵列。 对于青色和品红色,成对的两个阵列的相邻喷嘴之间的间隔设置为1/4的喷嘴间距。 对于青色和品红色,所有四个喷嘴阵列都以高分辨率打印模式使用,并且在正常打印模式下,四个喷嘴阵列中只有两个用于打印。 在成对的邻接喷嘴阵列中,仅使用一个。
