摘要： When the size of a printing paper is smaller than a half of the whole area used for expanding the printing data, a method and apparatus for controlling high speed printing in a printer device, having a bit-map memory, a data transfer circuit for transferring video data on the bit-map memory to a printer, and a copying unit for copying the dot-data within a rectangular region on the bit-map memory, include copying the dot-data expanded in a first area on the bit-map memory into a second area that does not overlap with the first area; and sending the dot-data to the printer, and simultaneously expanding the printing data of the next page in the first area. When the size of a printing paper is smaller than the whole area, the method and apparatus include copying the dot-data expanded in a first area on the bit-map memory into a second area that overlaps with the first area in one part; sending the dot-data to the printer; and expanding the printing data of the next page in the first area partially in parallel.

摘要翻译： 当打印纸的尺寸小于用于扩展打印数据的整个区域的一半时，一种用于在具有位图存储器的打印机设备中控制高速打印的方法和装置，用于传送的数据传送电路 将打印机的位图存储器上的视频数据和用于复制位图存储器上的矩形区域内的点数据的复制单元，包括复制扩展在位图存储器上的第一区域中的点数据 进入与第一区域不重叠的第二区域; 并将点数据发送到打印机，同时扩展第一区域中的下一页的打印数据。 当打印纸的尺寸小于整个区域时，该方法和装置包括将在位图存储器上的第一区域中扩展的点数据复制到与一个部分中与第一区域重叠的第二区域; 将点数据发送到打印机; 并且部分平行地扩展第一区域中的下一页的打印数据。
