Abstract

본 발명은 페이지 버퍼 메모리의 이용효율을 향상시킨 프린터에 관한 것이다. 종래의 프린터는 반복되는 데이터가 페이저 버퍼 메모리에 모두 저장되었으나, 본 발명에 의한 프린터는 반복되는 데이터는 그 중 맨처음 데이터만 페이지 버퍼 메모리에 저장하여 페이지 버퍼 메모리를 효율적으로 이용할 수 있다. 본 발명의 프린터는 컴퓨터로부터 전송된 데이터를 저장하되 반복되는 데이터는 하나의 정보만 저장하는 페이지 버퍼 메모리와, 상기 페이지 버퍼 메모리의 데이터를 읽어내고 그 중의 반복되는 데이터는 저장된 하나의 정보를 통하여 다른 반복되는 데이터를 이끌어내는 DMA 제어부 및 상기 DMA 제어기로부터 데이터를 받아서 비디오 데이터를 출력하는 프린터 인터페이스(interface) 제어기로 구성되어 있다.The present invention relates to a printer that improves the utilization efficiency of the page buffer memory. In the conventional printer, all the repeated data is stored in the pager buffer memory, but the printer according to the present invention can efficiently use the page buffer memory by storing only the first data among the repeated data in the page buffer memory. The printer of the present invention stores data transmitted from a computer, but repeats the page buffer memory for storing only one information, and reads the data of the page buffer memory, and the repeated data therein is stored through the other stored information. And a printer interface controller for receiving data from the DMA controller and outputting video data.
