Комментарии

Как и PrintQueue класс , это перечисление обрабатывает очередь печати и физический принтер (или устройство) как единое целое. Некоторые значения представляют состояние физического устройства, а другие — состояние программы очереди печати, запущенной на сервере печати.

Используйте это перечисление для предоставления значений QueueStatus для свойства PrintQueue класса .
