Answer 1

GetProfileString("windows","device",",,,",buf,80);

Answer 2

char dev[255],*dp;  GetProfileString("windows","device","",dev,255);
  if(strcmp(dev,"")==0) return;
  dp=strchr(dev,',');
  *dp='\0';  
  
    if(OpenPrinter(dev,&hPrint,NULL))
    { PrinterProperties(NULL,hPrint);
      ClosePrinter(hPrint) ;
    }

Answer 3

这个可能更好
EnumPrinters (dwFlags, NULL, 2, (LPBYTE) pPrinters,
          cbPrinters, &cbPrinters, &cReturned)
for (i = 0; i < cReturned; i++)
{
strcpy (szDeviceName, (pPrinters + i)->pPrinterName);
strcpy (szPort, (pPrinters + i)->pPortName);
strcpy (szDriverName, (pPrinters + i)->pDriverName);
memcpy (&InitData, (pPrinters + i)->pDevMode, sizeof(DEVMODE));
}
