저는 지금 데이터를 가져와서 그래프를 그리고 ,
화면을 출력하는 간단한 어플리케이션을 개발하고 있는데,
프린터를 할려고 하는데 아래와 같은 문제가 발생합니다.
아래 프로그램은 프린터관련 소스로 게시판에 올라와 있는 것인데
제가 잘 몰라서 그런지 paint() 메소드에서
graphics 를 몇개 추가하여 스트링을 화면에 그려 주었는데
화면에는 잘 나타나는데 ,
프린터로 출력을 하면 마지막의 g.drawString("AAAAAAAD",100,100); 에서 출력한
문자만 나타나고 나머지는 하나도 나타나지 않습니다..
왜 그런지 아시는 분은 제발 좀 도와 주십시오...
