-  EnumPrinters(param, null, level, buffer + offset, 512, &needed, &nprinters);
+  if (!EnumPrinters(param, null, level, buffer + offset, 512, &needed,
&nprinters)) {

   if (needed < 512)
     needed = 512;

explains:
when printer spooler is stopped, EnumPrinters returns false, and i fyou
call GetLastError() you'll get 1722, net helpmsg 1722 -> 'RPC server is
unavailable'
in this case, variable "needed" is not initialized, nor does "nprinters".
so simply return NULL in this case
