欄位

AutoSelect	1	根據紙張大小和媒體輸出類型自動選取輸入紙匣。
AutoSheetFeeder	4	使用自動送紙器。
Cassette	2	使用抽取式紙匣。
Manual	5	使用手動輸入紙匣。
Tractor	3	使用可連續送紙的曳引送紙 (也稱為孔式送紙)。
Unknown	0	功能 (其選項由這個列舉表示) 設定為 列印結構描述中未定義的選項。

範例

下列範例示範如何判斷印表機功能，並設定列印作業以利用它們。

備註

此類型的值主要用於下列用途：

• 做為集合成員的 InputBinCapability 屬性 PrintCapabilities，它們會指出印表機支援的輸入匣類型。

• 做為 的 InputBinPrintTicket屬性值，它們會指示印表機使用指定的量化。

值 Unknown 永遠不會用在 對象的屬性 PrintCapabilities 中。

您不應該將 PrintTicket 屬性設定為 Unknown。 如果某些其他 PrintTicket 產生應用程式已建立一份 PrintTicket 檔，將輸入 bin 功能設定為無法辨識的 optio， (也就是在 列印架構中未定義的選項，則 PrintTicket 以該檔建構的應用程式中的物件將會具有 Unknown 屬性的值 InputBin 。

PrintTicket雖然 無法繼承 和 PrintCapabilities 類別，但您可以擴充列印架構，以辨識未在 或 PrintCapabilities 類別中考慮的PrintTicket列印裝置功能。 如需詳細資訊，請參閱 如何：擴充列印架構和建立新的列印系統類別。
