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.
