Druckerstatus (PRINTER_ATTRIBUTE) auslesen

[TaFa]

Hallo ,
bin schon am verzweifeln.
Ich möchte Programmgesteuert herausfinden, ob der angeschlossene Drucker den Status ONLINE/OFFLINE hat.
Über PRINTER_INFO_5 kann ich PRINTER_ATTRIBUTE auslesen, was so weit funktioniert.
Wenn ich aber den Drucker über Windows (WIN7) auf offline setze, kriege ich den PRINTER_ATTRIBUTE-Wert=0x00000640 und auf Online 0x00000240 beide Werte sind aber in Winspool.h nicht definiert
Hat jemand ne Idee, ob die beiden Werte wirklich ON/OFFLINE-Status repräsentieren?

Das ist eine Bit Maske.
Also ist es sehr wohl definiert:

0x640 == PRINTER_ATTRIBUTE_LOCAL | PRINTER_ATTRIBUTE_DO_COMPLETE_FIRST | PRINTER_ATTRIBUTE_WORK_OFFLINE;
0x240 == PRINTER_ATTRIBUTE_LOCAL | PRINTER_ATTRIBUTE_DO_COMPLETE_FIRST;

Mit seinem switch case kommst Du da nicht hin:

if (pDrucker->Attributes & PRINTER_ATTRIBUTE_DIRECT)
    m_List.AddString("PRINTER_ATTRIBUTE_DIRECT            ");
if (pDrucker->Attributes & PRINTER_ATTRIBUTE_DO_COMPLETE_FIRST)
    m_List.AddString("PRINTER_ATTRIBUTE_DO_COMPLETE_FIRST    ");
...
