Hi everyone,

our small application which is a slightly modified Windows GENPRINT print
processor devlivered with the DDK (7600.16385.0 is currently used) works
since many years starting from XP, Vista, 2003, 2008 (either 32 and 64 bit).

But in Win7 (and most likely also Win2008 R2), the windows spooler system
crashes (PrintIsolationHost, see below for more details explanation) while
processing a print job in the function: EnumPrinters. To be more precise,
the job is sent to "nowhere" and the queue seems 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 crash. I posted th first log file entry, 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 Win7 inbox
printer driver.

What I 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 me!
