GetPrintCapabilities(PrintTicket)

プリンターの機能を識別する PrintCapabilities オブジェクトを取得します。

public:
 System::Printing::PrintCapabilities ^ GetPrintCapabilities(System::Printing::PrintTicket ^ printTicket);

public System.Printing.PrintCapabilities GetPrintCapabilities (System.Printing.PrintTicket printTicket);

member this.GetPrintCapabilities : System.Printing.PrintTicket -> System.Printing.PrintCapabilities

Public Function GetPrintCapabilities (printTicket As PrintTicket) As PrintCapabilities

パラメーター

printTicket

PrintTicket

印刷機能を報告するための基準となる印刷チケット。

戻り値

PrintCapabilities

両面処理や自動ステープル処理など、プリンターが実行できる処理および実行できない処理を指定する PrintCapabilities オブジェクト。

例外

PrintQueueException

PrintCapabilities オブジェクトを取得できませんでした。

ArgumentException

printTicket の形式が正しくありません。

注釈

パラメーターは PrintTicket 、オブジェクトを構築 PrintCapabilities するための基礎として使用されます。 たとえば、プリンターが入力ビン 1 のメディア・タイプ A と B のみをサポートし、入力ビン 2 のメディア・タイプ C のみをサポートしたとします。 パラメーターが printTicket 入力ビン 1 を指定した場合、 PrintCapabilities 返されるオブジェクトには 3 つのメディアの種類がすべて含まれますが、型 C は "制約付き" と報告されます。パラメーターが printTicket 入力ビン 2 を指定した場合、 PrintCapabilities 返されるオブジェクトには 3 つのメディアの種類がすべて含まれますが、型 A と B は "制約付き" として報告されます。制約の詳細については、「 印刷スキーマ 」を参照してください。

が のnull場合printTicket、 UserPrintTicket が使用されます。
