    • There are provided an image printing method and device. A print image is printed on a printing object, by relatively moving at least one of the printing object and a print head which has a plurality of dot elements arranged in a predetermined direction each for printing one pixel dot and is capable of printing a predetermined maximum number of pixel dots in the predetermined direction, in a direction orthogonal to the predetermined direction. An image having a number of pixel dots in the predetermined direction smaller in number than the predetermined maximum number of pixel dots is set to the print image. A range of use corresponding to a predetermined number of pixel dots is set to the plurality of dot elements. A printing position of the print image is adjusted in units of one or more pixel dots, as required, by moving the range of use along the predetermined direction. The print image is printed on a predetermined print area on the printing object by using dot elements in the range of use of the plurality of dot elements.
    • 提供了一种图像打印方法和装置。 通过相对移动打印对象和打印头中的至少一个,打印图像被打印在打印对象上,打印头具有以预定方向布置的多个点元素,用于打印一个像素点,并且能够打印预定的最大值 在与预定方向正交的方向上的预定方向上的像素点数。 将具有比预定的最大像素点数小的预定方向上的像素点数的图像设置为打印图像。 将与预定数量的像素点对应的使用范围设置为多个点元素。 通过沿预定方向移动使用范围,根据需要以一个或多个像素点为单位调整打印图像的打印位置。 通过使用多个点元素的使用范围中的点元素,将打印图像打印在打印对象的预定打印区域上。
