Abstract

본 발명은 패스북 프린터의 핸드 쉐이킹 방법에 관한 것으로, 이는 컴퓨터의 병렬 포트를 통해 패스북 프린터를 접속하였을 경우 패스북 프린터의 상태를 컴퓨터에게 좀더 정확하게 알려주어 리모트 패스북 컴퓨터의 상태를 자신의 컴퓨터에서 좀더 정확히 파악함으로써 패스북 프린터의 에러 상황의 대처 능력을 향상시키도록 한것이다.The present invention relates to a handshaking method of a passbook printer. When a passbook printer is connected through a parallel port of a computer, the passbook printer is notified of the state of the passbook printer to the computer more accurately, thereby indicating the state of the remote passbook computer. In order to better understand Passbook printer's ability to deal with error conditions,

이와같은 본 발명은 초기에 컴퓨터가 프린터 아답터를 통해 패스북 프린터에 제1, 제2상태요구 명령의 데이타를 송출하고 소정시간 경과 후 스트로브신호와 통화중신호를 송출하는 단계와; 상기 패스북 프린터측에서의 상기 프린터 아답터를 통해 전송되는 상태요구 명령 데이타를 수신버퍼를 통해 판독 분석하여 현재의 신호상태를 조작하고 그 분석한 결과 상태를 나타내면 이를 프린터 아답터를 통해 컴퓨터로 전송하는 단계와; 상기컴퓨터측에서의 상기 프린터 아답터를 통해 전송되는 상태신호를 읽어들여 판독하고 이에 대한 응답신호를 프린터 아답터를 통해 패스북 프린터에 송출하는 단계로 이루어짐으로서 달성된다.As described above, the present invention includes the steps of: a computer initially transmitting data of a first and second status request command to a passbook printer through a printer adapter and transmitting a strobe signal and a busy signal after a predetermined time; Reading and analyzing the status request command data transmitted through the printer adapter at the passbook printer through a reception buffer to manipulate the current signal status and transmitting the current signal status to the computer through the printer adapter; And reading out and reading the status signal transmitted through the printer adapter at the computer side and sending a response signal to the passbook printer through the printer adapter.
