);
HRESULT put_Location(
  [in] BSTR bstrLocation
);

Model

The name of the driver used by this print queue.

Access type: Read/write

Scripting data type: BSTR

// C++ method syntax
HRESULT get_Model(

PrinterPath

The string that references the path by which a shared printer can be accessed.

HRESULT put_PrinterPath(
  [in] BSTR bstrPrinterPath

Access type: Read/write

Scripting data type: BSTR

// C++ method syntax
HRESULT get_PrintProcessor(
  [out] BSTR* pbstrPrintProcessor
);
HRESULT put_PrintProcessor(
  [in] BSTR bstrPrintProcessor
);

Priority

The priority of this printer object job queue for any connected devices. All jobs in higher priority print queue objects will be processed first.

Access type: Read/write

Scripting data type: LONG

// C++ method syntax
HRESULT get_Priority(
  [out] LONG* plPriority
);
HRESULT put_Priority(
  [in] LONG lPriority
);

StartTime

The time when the queue should begin processing jobs. The date portion of the time is ignored.

Scripting data type: DATE

// C++ method syntax
HRESULT get_StartTime(
  [out] DATE* pdateStartTime
);
HRESULT put_StartTime(
  [in] DATE dateStartTime
);

UntilTime

The time when the queue should stop processing jobs.

Access type: Read/write

Scripting data type: DATE

// C++ method syntax
HRESULT get_UntilTime(
  [out] DATE* pdateUntilTime
);
HRESULT put_UntilTime(
  [in] DATE dateUntilTime
);

Examples

The following code example shows how to determine if a specified printer is online or offline.

Dim pq As IADsPrintQueue
Dim pqo As IADsPrintQueueOperations
On Error GoTo Cleanup
 
Set pq = GetObject("WinNT://aMachine/aPrinter")
Set pqo = pq
If pqo.status = ADS_PRINTER_OFFLINE Then
    MsgBox pq.Model & "@" & pq.Location & is offline."
Else
    MsgBox pq.Model & "@" & pq.Location & is online."
End If

Cleanup:
    If (Err.Number<>0) Then
        MsgBox("An error has occurred. " & Err.Number)
    End If
    Set pq = Nothing
    Set pqo = Nothing

The following code example shows how to determine if a specified printer is online or offline.

IADsPrintQueue *pq = NULL;
HRESULT hr = S_OK;
IADsPrintQueueOperations *pqo = NULL;
BSTR model = NULL;
BSTR location = NULL;

LPWSTR adsPath = L"WinNT://aMachine/aPrinter";
hr = ADsGetObject(adsPath,
                  IID_IADsPrintQueue,
                  (void**)&pq);
if(FAILED(hr)) {goto Cleanup;}


hr = pq->QueryInterface(IID_IADsPrintQueueOperations,(void**)&pqo);
if(FAILED(hr)) {goto Cleanup;}

long status;
hr = pqo->get_Status(&status);
if(FAILED(hr)) {goto Cleanup;}

hr = pq->get_Model(&model);
if(FAILED(hr)) {goto Cleanup;}

hr =pq->get_Location(&location);
if(FAILED(hr)) {goto Cleanup;}

if(status == ADS_PRINTER_OFFLINE) 
{
    printf("%S @ %S is offline.\n",model,location);
} 
else 
{
    printf("%S @ %S is online.\n",model,location);
}


Cleanup:
    SysFreeString(model);
    SysFreeString(location);
    if(pq) pq->Release();
    if(pqo) pqo->Release();
