下面这段代码能列出当前的系统上的打印机
#include <winspool.h>
DWORD dwSize,dwPrinters;
::EnumPrinters(PRINTER_ENUM_LOCAL,NULL,5,NULL,0,&dwSize,&dwPrinters);
BYTE *pBuffer=new BYTE[dwSize];
::EnumPrinters(PRINTER_ENUM_LOCAL,NULL,5,NULL,pBuffer,&dwSize,&dwPrinters);
if(dwPrinters!=0)
{
PRINTER_INFO_5 *pPrnInfo=(PRINTER_INFO_5 *)pBuffer;
for(int i=0;i<dwPrinters,i++)
{
cout<<pPrnInfo->pPrinterName<<endl;
pPrnInfo++;//指针后移
}
}
delete []pBuffer;
