SAMBA 공유 프린터를 통해 CUPS로 인쇄하는 것이 느립니다.

CUPS를 실행하는 Debian 인쇄 서버가 있습니다. CUPS에서는 IPP를 통해 네트워크 프린터에 연결된 원시 인쇄 대기열을 구성합니다.

또한 저는 상당히 표준적인 smb.conf 옵션과 CUPS를 백엔드로 사용하여 Samba 프린터 공유를 통해 Windows 사용자와 이 프린터를 공유합니다.

IPP를 사용하여 Windows에서 CUPS 대기열로 직접 인쇄하는 경우(예:http://cups-server:631/printers/프린터 이름), 프린터가 빠르게 반응하고 거의 즉각적으로 인쇄합니다.

그러나 Windows에서 공유 Samba 프린터를 통해 인쇄 대기열로 인쇄하는 경우 프린터가 프린터 속성 창을 여는 데 15초 이상이 걸리고 테스트 페이지를 인쇄하는 데에도 같은 시간이 걸립니다.

원인을 추론하는 동안 두 개의 서로 다른 인쇄 서버와 프린터, 여러 개의 서로 다른 Windows 클라이언트가 있는 두 개의 완전히 분리된 네트워크에서 문제를 재현할 수 있었기 때문에 이것이 개인 설치에만 국한된 것은 아니라고 생각합니다. IP 주소와 호스트 이름을 모두 사용하면 동일한 동작이 발생합니다.

Samba 공유 프린터로 인쇄 속도를 높이기 위해 옵션이나 설정을 조정해야 합니까?

저는 CUPS 2.2.1과 Samba 4.5.12를 실행하고 있습니다. CUPS 1.7.5 및 Samba 4.2.14를 실행하는 이전 서버에서도 동일한 동작을 재현할 수 있습니다.

내 smb.conf는 다음과 같습니다. 인쇄 제목 아래 처음 4개 옵션을 제외하고 모든 것이 Debian smb.conf의 기본값입니다.
