Gör så här: Diagnostisera problematiskt utskriftsjobb

Artikel
12/18/2024

Nätverksadministratörer får ofta klagomål från användare om utskriftsjobb som inte skrivs ut eller skrivs ut långsamt. Den omfattande uppsättningen utskriftsjobbegenskaper som exponeras i API:erna för Microsoft .NET Framework är ett sätt att utföra en snabb fjärrdiagnos av utskriftsjobb.

Exempel

De viktigaste stegen för att skapa den här typen av verktyg är följande.

Identifiera utskriftsjobbet som användaren klagar på. Användarna kan ofta inte göra detta exakt. De kanske inte känner till namnen på utskriftsservrarna eller skrivarna. De kan beskriva skrivarens plats i en annan terminologi än vad som användes för att ange dess Location egenskap. Därför är det en bra idé att generera en lista över användarens för närvarande skickade jobb. Om det finns fler än en kan kommunikationen mellan användaren och utskriftssystemets administratör användas för att hitta det jobb som har problem. Understegen är följande.
1. Hämta en lista över alla utskriftsservrar.
2. Loopa genom servrarna för att köra frågor mot deras utskriftsköer.
3. Inom varje pass i serverloopen genomför du en genomgång av alla serverns köer för att förfråga deras jobb.
4. I varje passering av köloopen loopar du igenom dess jobb och samlar in identifierande information om dem som skickats av den klagande användaren.
När det problematiska utskriftsjobbet har identifierats undersöker du relevanta egenskaper för att se vad som kan vara problemet. Är jobbet till exempel i ett feltillstånd eller gick skrivaren som betjänar kön offline innan jobbet kunde skrivas ut?

Koden nedan är en serie kodexempel. Det första kodexemplet innehåller loopen via utskriftsköerna. (Steg 1c ovan.) Variabeln myPrintQueues är det PrintQueueCollection objektet för den aktuella utskriftsservern.

Kodexemplet börjar med att uppdatera det aktuella utskriftsköobjektet med PrintQueue.Refresh. Detta säkerställer att objektets egenskaper korrekt representerar tillståndet för den fysiska skrivare som det representerar. Sedan hämtar programmet samlingen med utskriftsjobb som för närvarande finns i utskriftskön med hjälp av GetPrintJobInfoCollection.

Därefter loopar programmet igenom PrintSystemJobInfo-samlingen och jämför varje Submitter egenskap med aliaset för den klagande användaren. Om de matchar lägger programmet till identifierande information om jobbet i strängen som ska visas. (Variablerna userName och jobList initieras tidigare i programmet.)

for each (PrintQueue^ pq in myPrintQueues)
{
   pq->Refresh();
   PrintJobInfoCollection^ jobs = pq->GetPrintJobInfoCollection();
   for each (PrintSystemJobInfo^ job in jobs)
   {
      // Since the user may not be able to articulate which job is problematic,
      // present information about each job the user has submitted.
      if (job->Submitter == userName)
      {
         atLeastOne = true;
         jobList = jobList + "\nServer:" + line;
         jobList = jobList + "\n\tQueue:" + pq->Name;
         jobList = jobList + "\n\tLocation:" + pq->Location;
         jobList = jobList + "\n\t\tJob: " + job->JobName + " ID: " + job->JobIdentifier;
      }
   }
}

foreach (PrintQueue pq in myPrintQueues)
{
    pq.Refresh();
    PrintJobInfoCollection jobs = pq.GetPrintJobInfoCollection();
    foreach (PrintSystemJobInfo job in jobs)
    {
        // Since the user may not be able to articulate which job is problematic,
        // present information about each job the user has submitted.
        if (job.Submitter == userName)
        {
            atLeastOne = true;
            jobList = jobList + "\nServer:" + line;
            jobList = jobList + "\n\tQueue:" + pq.Name;
            jobList = jobList + "\n\tLocation:" + pq.Location;
            jobList = jobList + "\n\t\tJob: " + job.JobName + " ID: " + job.JobIdentifier;
        }
    }// end for each print job
}// end for each print queue

For Each pq As PrintQueue In myPrintQueues
    pq.Refresh()
    Dim jobs As PrintJobInfoCollection = pq.GetPrintJobInfoCollection()
    For Each job As PrintSystemJobInfo In jobs
        ' Since the user may not be able to articulate which job is problematic,
        ' present information about each job the user has submitted.
        If job.Submitter = userName Then
            atLeastOne = True
            jobList = jobList & vbLf & "Server:" & line
            jobList = jobList & vbLf & vbTab & "Queue:" & pq.Name
            jobList = jobList & vbLf & vbTab & "Location:" & pq.Location
            jobList = jobList & vbLf & vbTab & vbTab & "Job: " & job.JobName & " ID: " & job.JobIdentifier
        End If
    Next job ' end for each print job

Next pq ' end for each print queue

Nästa kodexempel hämtar programmet i steg 2. (Se ovan.) Det problematiska jobbet har identifierats och programmet frågar efter den information som ska identifiera det. Från den här informationen skapas PrintServer, PrintQueueoch PrintSystemJobInfo objekt.

I det här läget innehåller programmet en förgreningsstruktur som motsvarar de två sätten att kontrollera statusen för ett utskriftsjobb:

Du kan läsa flaggorna för egenskapen JobStatus som är av typen PrintJobStatus.
Du kan läsa varje relevant egenskap, till exempel IsBlocked och IsInError.

Det här exemplet visar båda metoderna, så användaren uppmanades tidigare att ange vilken metod som ska användas och svarade med "Y" om de ville använda flaggorna för egenskapen JobStatus. Se nedan för information om de två metoderna. Slutligen använder programmet en metod som heter ReportQueueAndJobAvailability för att rapportera om jobbet kan skrivas ut vid den här tiden på dagen. Den här metoden beskrivs i Identifiera om ett utskriftsjobb kan skrivas ut vid den här tidpunkten på dagen.

Om du vill kontrollera utskriftsjobbets status med hjälp av flaggorna för egenskapen JobStatus kontrollerar du varje relevant flagga för att se om den har angetts. Standardsättet för att se om en bit anges i en uppsättning bitflaggor är att utföra en logisk AND-åtgärd med uppsättningen flaggor som en operand och själva flaggan som den andra. Eftersom själva flaggan bara har en bit satt är resultatet av det logiska OCH-operationen att som mest kan vara satt samma bit. Om du vill ta reda på om det är det eller inte kan du bara jämföra resultatet av det logiska OCH med själva flaggan. Mer information finns i PrintJobStatus, & Operator (C#-referens)och FlagsAttribute.

För varje attribut vars bit har angetts rapporterar koden detta till konsolskärmen och föreslår ibland ett sätt att svara. (Metoden HandlePausedJob som anropas om jobbet eller kön har pausats beskrivs nedan.)

Metoden HandlePausedJob gör det möjligt för programmets användare att fjärransluta och återuppta pausade jobb. Eftersom det kan finnas en bra anledning till att utskriftsköen pausades börjar metoden med att fråga efter ett användarbeslut om huruvida den ska återupptas. Om svaret är "Y" anropas metoden PrintQueue.Resume.

Därefter uppmanas användaren att bestämma om själva jobbet ska återupptas, ifall det pausas oberoende av utskriftskö. (Jämför PrintQueue.IsPaused och PrintSystemJobInfo.IsPaused.) Om svaret är "Y" anropas PrintSystemJobInfo.Resume; annars anropas Cancel.
