Ну пока ни чего.
Тут надо определиться что мы хотим именно получить:
enable/disable определённого принтера
конфигурирование принтера, если он ещё не был добавлен.

В последнем случае будем пытаться делать полную автоматику или будем вызывать какой интерфейс?

Что касается первого то при отключении устройства от hal насколько я
наблюдал приходит инфомация содержащая какой-то внутренний идентификатор
принтера, соотв. надо где-то генерить и хранить таблицу между этими
идентификаторами и именами очередей в cups.

Товарищ, который писал письмо, многое сделал руками под свой конкретный
случай.
