이베이에서 비닐 절단기를 찾아서 구입했습니다.
그러던 중 우연히 다음 영상을 발견했습니다.https://www.youtube.com/watch?v=3tZXsUGEJ-E이는 이러한 유형의 장치가 Linux에서 사용될 수 있음을 보여줍니다. inkcut을 설치했지만 장치에 연결하는 방법을 잘 모르겠습니다.
lsusb -v이 장치가 주어지면:

나는 온라인에서 다양한 기사를 읽었으며 그 중 일부는 언급되었습니다.udev 규칙잠깐만요. 하지만 상관없이 돌아올 겁니다 ls -l /dev/ttyUSB*.ls: cannot access '/dev/ttyUSB*': No such file or directory
내가 무엇을 놓치고 있나요?
답변1
문제는 내가 생각했던 것이 아니었음이 밝혀졌습니다.
프린터가 연결된 USB LP 장치(usblp2)로 나타나는 것을 확인합니다 /dev/usb/lp2. 이는 병렬 포트를 선택해야 함을 의미합니다. 이는 inkcut에서 직접 발생하지 않지만 다시 시작해야 합니다.
