Название принтеров в сети

[Чудик]

Как узнать все названия принтеров в локальной сети?

GetPrinter

[Чудик]

Если не ошибаюсь, для GetPrinter необходимо знать манипулятор принтера. Соответственно, как можно узнать манипуляторы всех принтеров в сети?

[Scuder]

Возвращает название, путь и т.п. принтера, использующегося по умолчанию. Не копал. Может, и по всем можно пробежаться..

Нашел такую функцию как EnumPrinters.
В том же API-Guide есть пример на заполнение списка принтерами в сети.
