I have trouble printing documents from a Classic application. I've tried everything I found in Mac Help but I still get this message: "Le port série est déjà utilisé par une autre application. Quittez cette application et relancez l'impression." I didn't print anything from an other application and I didn't have any other application open. I tried it several times from two different Classic applications, I restarted the computer and it is still not working. What should I do?
