Abstract

본 발명은 공라인을 페이지 버퍼 메모리에 저장하지 않고 처리함으로써 페이지 버퍼 메모리의 이용효율을 향상시킨 프린터에 관한 것이다. 종래의 프린터는 공라인도 페이지 버퍼 메모리에 저장되었으나, 본 발명은 공라인은 페이저 버퍼 메모리에 저장되지 않기 때문에 페이저 버퍼 메모리를 효율적으로 이용할 수 있을 뿐만 아니라 불필요하게 페이지 버퍼 메모리를 접근하는 시간을 단축하여 버스이용효율을 향상시킬 수가 있다. 본 발명의 구성은 컴퓨터로부터 전송된 데이터를 일시저장하는 페이지 버퍼 메모리와, 상기 페이지 버퍼 메모리의 데이터를 읽어내는 DMA 제어기와, 상기 DMA 제어기로부터 데이터를 받아서 인쇄할 수 있도록 비디오 데이터를 출력하는 프린터 인터페이스(interface)제어부로 되어 있다.The present invention relates to a printer which improves the utilization efficiency of the page buffer memory by processing the empty lines without storing them in the page buffer memory. In the conventional printer, the empty line is stored in the page buffer memory. However, in the present invention, since the empty line is not stored in the pager buffer memory, the pager buffer memory can be efficiently used and the time for accessing the page buffer memory is unnecessary. Therefore, bus utilization efficiency can be improved. The configuration of the present invention includes a page buffer memory for temporarily storing data transmitted from a computer, a DMA controller for reading data of the page buffer memory, and a printer interface for outputting video data to receive and print data from the DMA controller. (interface) control unit.
