На случай, если кому-то это понадобится, я придумал обходной путь, основанный на сохранении блока памяти настроек принтера в двоичном файле с последующим его восстановлением. Идея описана в это сообщение в блоге, но оно не сработало для меня при простом копировании (оно работало только для некоторых драйверов и некоторых настроек, тогда как другие параметры печати были проигнорированы).
Поэтому я немного переделал его, чтобы теперь он мог поддерживать все настройки, которые я пробовал на любом принтере (с совместимым драйвером), который я тестировал. Конечно, если вы используете драйвер другого принтера, например, он не сработает.
Недостатком этого подхода, конечно же, является то, что вы должны сначала установить настройки принтера по умолчанию (в Панели управления) на то, что вам нужно. Конечно, это не всегда возможно, но, по крайней мере, в некоторых случаях это может помочь.
Итак, полный исходный код тестовой утилиты, которая может сохранять настройки принтера в файл, снова загружать этот файл в принтер и распечатывать документ, используя указанный файл настроек:

ОБНОВЛЕНИЕ 04.12.2018 (через 5,5 лет): Была неприятная редкая проблема с вызовом Marshal.StructureToPtr в этом коде, и сегодня я наконец получил ответ на этот вопрос (см. комментарий Ганса Пассанта). Я не могу проверить, действительно ли это работает, поскольку я больше не работаю над этим проектом, но, похоже, вам может потребоваться применить это исправление, если вы попытаетесь использовать этот код.
