Thank you for the music

POI 엑셀 API에서 프린트에 관련된 옵션을 지정하기 위해서 "HSSFPrintSetup" 클래스를 사용해야 한다.

http://poi.apache.org/apidocs/org/apache/poi/hssf/usermodel/HSSFPrintSetup.html

위 URL에 HSSFPrintSetup 클래스의 도큐먼테이션이 되어 있다.

HSSFSheet sheet = workbook.createSheet("Sheet1");
//인쇄 옵션 클래스 선언
HSSFPrintSetup print = sheet.getPrintSetup();

//인쇄 용지를 A4로 설정
print.setPaperSize(HSSFPrintSetup.A4_PAPERSIZE);

//인쇄 방향을 가로로 설정 true면 가로 false면 세로(default)
print.setLandscape(true);

//인쇄시 확대/축소 배율
print.setScale( (short) 80 );

위와 같이 사용하면 된다

HSSFPrintSetup 클래스에 상수는 위와 같이 인쇄 종이 유형이 상수로 잡혀있따

A4(9), A5(11) 을 아무래도 많이 쓸듯 싶다.
