TCP/IP 已安裝建構包含 MIB 表格列的物件 ID (OID) 及查閱值清單。 If any of the lookup values exists in the row, this algorithm returns TRUE. 大部分與印表機設定相關的查詢都應該判斷印表機的 MIB 中是否有儲存的特定值,然後傳回布林結果。 Installed 建構定義在 Tcpbidi.xsd 中。
| Attribute | Description |
|---|---|
| deviceIndex | (Optional) A flag that, when TRUE, means that the associated algorithm must include the device index in the specified OID; when FALSE, a trailing zero is appended to the OID. The default value is FALSE. For more information, see the note on the page for Value. |
| drvPrinterEvent | (選擇性)布爾值,指出埠監視器是否傳送通知給驅動程式。 A TRUE value indicates that the port monitor sends notifications to the driver; FALSE indicates that the port monitor does not send notifications to the driver. |
| name | 架構值的名稱。 |
| oid | MIB 資料表的資料列,作為 OID。 |
| refreshInterval | 輪詢間隔的值,以秒為單位。 預設值為 600 秒。 |
Code Example
In the following code example, the lookup algorithm retrieves the MIB table row from 1.3.6.1.2.1.43.13.4.1.9.<deviceIndex>. If this table row contains either 3 or 4, the query returns TRUE; otherwise the query returns FALSE.
<Property name="DuplexUnit">
<Installed name="Installed" oid="1.3.6.1.2.1.43.13.4.1.9" deviceIndex="true">
<Lookup value="3"/>
<Lookup value="4"/>
</Installed>
</Property>
上述範例會產生下列查詢:
\Printer.Configuration.DuplexUnit:Installed
