Can't get print job notification with status JOB_STATUS_DELETED - c++

Question

I want to get notification when print job has been completed or deleted. Now I see that notification mechanism provides the JOB_STATUS_DELETING, but no JOB_STATUS_DELETED status can be got.
I found something similar Here, but it doesn't solve my problem.
I'm doing next thing:
HANDLE hChange = FindFirstPrinterChangeNotification(hPrinter,
PRINTER_CHANGE_ALL,
0,
&NotificationOptions);
DWORD dwChange;
HANDLE aHandles[2];
aHandles[0] = hChange;
aHandles[1] = owner->GetStopRequestEvent();
while (hChange != INVALID_HANDLE_VALUE)
{
// sleep until a printer change notification wakes this thread or the
// event becomes set indicating it's time for the thread to end.
WaitForMultipleObjects(2, aHandles, FALSE, INFINITE);
if (WaitForSingleObject(hChange, 0U) == WAIT_OBJECT_0)
{
FindNextPrinterChangeNotification(hChange, &dwChange, &NotificationOptions, (LPVOID *) &pNotification);
if (pNotification != NULL)
{
// if a notification overflow occurred,
if (pNotification->Flags & PRINTER_NOTIFY_INFO_DISCARDED)
{
DWORD dwOldFlags = NotificationOptions.Flags;
// we must refresh to continue
NotificationOptions.Flags = PRINTER_NOTIFY_OPTIONS_REFRESH;
FreePrinterNotifyInfo(pNotification);
FindNextPrinterChangeNotification(hChange, &dwChange, &NotificationOptions, (LPVOID *) &pNotification);
NotificationOptions.Flags = dwOldFlags;
}
// iterate through each notification
for (DWORD x = 0; x < pNotification->Count; x++)
{
PRINTER_NOTIFY_INFO_DATA data = pNotification->aData[x];
if (data.Type == JOB_NOTIFY_TYPE)
{
if (data.Field == JOB_NOTIFY_FIELD_STATUS)
{
if (data.NotifyData.adwData[0] & ( JOB_STATUS_DELETED | JOB_STATUS_DELETING | JOB_STATUS_PRINTED))
{
owner->SendJobsData(data.NotifyData.adwData[0]);
}
......
when i delete job, JOB_NOTIFY_FIELD_STATUS passes only DELETING, and no any further status-notification, but I really need to get DELETED status. What am I doing wrong?

If anyone will face such task I will leave my way which I solve it.
I've noticed that every time when job leaves queue, the PRINTER_CHANGE_JOB_DELETE notification (i mean change of FindNextPrinterChangeNotification).
So, I just track task list in thread-owner class (JobTracker), and refresh it every time on any PRINTER_CHANGE_JOB. But before refresh it, I look at the difference and if I see that some job dissapeared (compare by JobId), I take my vector of jobs, and send to server missing job.
