How to get printer category(type)?

I'm trying to get printer category such as "Fax", or "Printer" which I can see in printer property window.

All I found is that I can get it from DRIVER_INFO_8,

DWORD dwNeeded;
LPBYTE lpDriverInfo;
DWORD dwReturned;
DRIVER_INFO_8 *pInfo;
DWORD i;

EnumPrinterDrivers(NULL,
    NULL,
    8,
    NULL,
    0,
    &dwNeeded,
    &dwReturned);

lpDriverInfo = new BYTE[dwNeeded];
if (lpDriverInfo == NULL) {
    return NULL;
}

EnumPrinterDrivers(NULL,
    NULL,
    8,
    lpDriverInfo,
    dwNeeded,
    &dwNeeded,
    &dwReturned);

pInfo = (DRIVER_INFO_8 *)lpDriverInfo;

but pInfo->dwDriverAttribute doesnt show PRINTER_DRIVER_CATEGORY_FAX, there is on

    dwlMinInboxDriverVerVersion 0   unsigned __int64

So I'm a bit confused - how can I get printer type?

To get the PRINTER_DRIVER_CATEGORY_FAX flag, you need at least windows 8 or windows server 2012 (http://msdn.microsoft.com/en-us/library/windows/desktop/dd162507(v=vs.85).aspx).

Try to use EnumPrinters with PRINTER_INFO_2 instead. You can then test for PRINTER_ATTRIBUTE_FAX
