PrintProcessor crashed in EnumPrinters() function in Windows 7 RRS feed

  • Question

  • Hello,

    Happy new year! I hope someone can help us. We do have since over 10 years a small application running in the more or less standard windows genprint prinprocessor, which is delivered with the DDK:


    But in   Windows 7, and most possibly with Windows 2008 R2, the windows spooler system crashes while processing a print job in the function: EnumPrinters. To be more precise, the job is sent to the nirvana and the queue seem to be ready for the next job.


    For test purposes we downsized to the original genprint from the DDK. In the file raw.cpp we added just one more function to write a debug file, which works perfectly.


    Then right at the beginning of the function PrintRawJob()   a the simple EnumPrinters() call for get back the needed amount of output bytes for calling the function with PRINTER_INFO_2 is added like this:



    DocInfo.pDatatype   = pData->pDatatype;     /* Document data type */


    {  /* new for testing */

        DWORD chNeeded=0, chReturned=0;

        WriteAppendDebugFile("Debug in file before EnumPrinters \n");


         EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 2, NULL, 0, &chNeeded, &chReturned);


        WriteAppendDebugFile("Debug in file after EnumPrinters \n");

    } /* new for testing */


    /** Let the printer know we are starting a new document **/

    if (!StartDocPrinter(pData->hPrinter, 1, (LPBYTE)&DocInfo)) {



    The result is unfortunately a windows 7 crash. Our first log file entry is there, the second never shows up. As only one more additional line (EumFunction) was added, the trouble maker must be it.   Of course we used a standard Windows 7 provided driver.


    What we try to find out with EnumPrinters is, which locally installed queue does use which print processor. Is there another reliable way to get this information, which runs in a print processor without using the EnumPrinters Function?


    Thank you so much for helping us:
