Как получить имя локально установленного принтера

Принтер по умолчанию:

#include <winspool.h>

void FindDefaultPrinter(OUT CString& strPrinterName) {
strPrinterName.Empty();
DWORD dwBytesNeeded, dwPrtRet2;
EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 2, NULL, 0, &dwBytesNeeded, &dwPrtRet2);

LPPRINTER_INFO_2 pPrtInfo2 = NULL;

TCHAR szErr[128] = {0};

try {
pPrtInfo2 = (LPPRINTER_INFO_2) LocalAlloc (LPTR, dwBytesNeeded);

if (!pPrtInfo2) {
_stprintf(szErr, TEXT("FindDefaultPrinter - Error! Function LocalAlloc fails!"));
throw 1;
}

BOOL res = EnumPrinters(PRINTER_ENUM_LOCAL, // types of printer objects to enumerate
NULL, // name of printer object
2, // specifies type of printer info structure
(LPBYTE)pPrtInfo2, // pointer to buffer to receive printer info structures
dwBytesNeeded, // size, in bytes, of array
&dwBytesNeeded, // pointer to variable with no. of bytes copied (or required)
&dwPrtRet2); // pointer to variable with no. of printer info. structures copied
if (!res) {
_stprintf(szErr, TEXT("FindDefaultPrinter - Error! Function EnumPrinters fails!"));
throw 1;
}

for (DWORD j=0; j<dwPrtRet2; j++) {
LPTSTR pPrinterName = (pPrtInfo2+j)->pPrinterName;
DWORD lenBuffer = _tcslen(pPrinterName)+1;
BOOL res = GetDefaultPrinter(pPrinterName, &lenBuffer);
if (res) {
strPrinterName = pPrinterName;
break;
}
}

//strPrinterName = pPrtInfo2->pPrinterName;
} catch(...) {}

if (pPrtInfo2)
LocalFree(pPrtInfo2);

if (*szErr) {
// Вывод ошибки
}
}
