paperbak은 binary로 되어 있는 파일을 그림파일(Dot Matrix)형태로 바꿔서 저장할 수 있게 만드는 것을 말한다.
참고로 paperbak은 bitmap과 종이에 QR코드랑 비슷하게 변환해서 데이터를 저장하게 만드는 것이다.
해당 코드를 제작한 사이트는 다음과 같다.
링크 : http://ollydbg.de/Paperbak/
이것을 bitmap으로 변환되어 있는 것을 이용해서 photos에 저장하니, 문제 없이 무한 클라우드 처럼 사용을 할 수 있게 되었다.(참고로 이걸 이용해서 파일을 저장하니 무손실로 데이터를 저장할 수 있었다.)

여기서 프린터에 대해서 설정하는 것이다.
간단하게, Dot Matrix로 저장하기 위한 것으로 printer.cpp에 사용하기 위한 구조체와 함수 선언이다.
함수 선언에서는 printer setting의 설정과, printing하기 위한 세팅 및 처리이다.

Scanner라고해서, Bitmap으로 저장되어 있는 Dot Matrix와 외부 Scanner에 대해서 연결해서 사용할 수 있는 TWAIN 라이브러리를 연결해서 사용한다.
※ TWAIN란, 외부 스캐너를 컨트롤을 하기 위해서 윈도우나 리눅스에서 지원해주는 드라이버이다.
이 드라이버를 이용해서 외부 스캐너에 연결되어 컨트롤을 할 수 있게 된다.
보기만해도 알 수 있듯. Scanner는 기본적으로 TWAIN을 위한 함수 선언들이 대부분이다.
Bitmap에 대해서 컨트롤하는 용도로 Decodebitmap이라는 것을 이용한다.
이 함수를 이용하면, 도움이 될 것이다.
여기서 TWAIN은 외부 스캐너에 연동되서 스캔을 하는 것이기 때문에, TWAIN는 다른 용도로 쓸 수도 있다.

Decoder라는 곳에서 페이지의 디코딩을 할때, 사용하는 구조체 및 함수들이다.
나머지 선언들은, Win32등을 이용해서, Windows창을 띄우기 위해 선언하는 구조체와 함수들로 보인다.
User Interface에 대해서는 조금더 찾아봐야 될 것 같긴하지만, 이것은 딱히 필요는 하지 않아 보인다.
