    • A printing method and apparatus in which basic image data and information of the printing position of the image data on a recording medium are input from a data source and stored in advance, and the designated image data is bitmapped at the printing position to print an image, thereby increasing the printing speed, and a printing system including the printing apparatus. In this system, image data sent from a host is registered as a basic image, and the image is bitmapped in an image memory on the basis of the information of the printing position, of the stored basic image data on a printing paper sheet, sent from the host. The image data bitmapped in the image memory is then output to a printhead to print the image. When the bitmapped image data is to be copied to a print buffer on the basis of an image copy command, the copy operation is preferably performed concurrently with registering operation for an image management table and bitmapping operation for an image registration buffer which are performed when image data different from the image data to be copied is input. In addition, the registered image data may be stored in one print buffer, and the registered image data may be copied to another print buffer on the basis of another command. Printout operation may be performed on the basis of the copied image data.
    • 一种打印方法和装置,其中基本图像数据和记录介质上的图像数据的打印位置的信息从数据源输入并预先存储,并且指定的图像数据在打印位置被位图打印以形成图像 从而提高打印速度,以及包括打印装置的打印系统。 在该系统中,将从主机发送的图像数据登记为基本图像,并且将图像根据打印位置的信息在存储在打印纸上的所存储的基本图像数据的位置映射到图像存储器中,发送 从主机。 然后将图像存储器中位图的图像数据输出到打印头以打印图像。 当基于图像复制命令将位图图像数据复制到打印缓冲器时,优选地对图像管理表的登记操作和图像登记缓冲器的位图操作同时进行复制操作,该图像登记缓冲器在图像 输入与要复制的图像数据不同的数据。 此外,可以将注册的图像数据存储在一个打印缓冲器中,并且可以基于另一个命令将登记的图像数据复制到另一打印缓冲器。 可以基于复制的图像数据执行打印输出操作。
