Centos 6 распознает и настраивает принтер HP LaserJet P3015dn, подключенный через USB. Этот аппарат настраивается как файловый сервер / сервер печати небольшой группы. Могу распечатать тестовую страницу, которая обработана / распечатана правильно. При следующей попытке печати (скажем, печати второй тестовой страницы) страница не печатается, и принтер отключен. Состояние принтера указано как:
Stopped - /usr/lib/cups/backend/hp failed
в диалоговом окне конфигурации принтера.
/var/log/cups/error_log содержит эту информацию (первые две строки были там до неудачного задания на печать)

Теперь я не понимаю, как продолжить работу с этим принтером на моей машине Centos. Как я могу настроить аппарат для печати более одного задания на печать без необходимости повторного отключения / подключения?
HP LaserJet P3015dn - это принтер, полностью поддерживаемый Linux и CUPS. Обозначение «dn» означает «дуплекс и сеть». Таким образом, быстрый и чистый способ исключить вашу рабочую станцию и (черт возьми) USB-подключение - это подключить этот принтер через Ethernet. В любом случае, это, вероятно, лучший подход к долгосрочному использованию.
Рассматривали ли вы возможность связаться с HP для получения возможных обновлений драйверов принтера и / или прошивки?
