这个api只能在2000下用，并且如果你的visual studio的Service pack较低的话，可能会找不到它。

Windows 95/98/Me: Unsupported.
Header: Declared in Winspool.h; include Windows.h.

#include <windows.h>

HDC GetPrinterDC(void)
{
DWORD dwNeeded, dwReturned;
HDC hdc;
PRINTER_INFO_4 *pinfo4;
PRINTER_INFO_5 *pinfo5;

if(GetVersion()&0x80000000) // Windows 98
{
EnumPrinters(PRINTER_ENUM_DEFAULT, NULL, 5, NULL, 0, &dwNeeded, &dwReturned);
pinfo5=malloc(dwNeeded);
EnumPrinters(PRINTER_ENUM_DEFAULT,NULL,5,(PBYTE)pinfo5,dwNeeded,&dwNeeded,&dwReturned);
hdc=CreateDC(NULL,pinfo5->pPrinterName,NULL,NULL);
free(pinfo5);
}
else // Windows NT
{
EnumPrinters(PRINTER_ENUM_LOCAL,NULL,4,NULL,0,&dwNeeded,&dwReturned);
pinfo4=malloc(dwNeeded);
EnumPrinters(PRINTER_ENUM_LOCAL,NULL,4,(PBYTE)pinfo4,dwNeeded,&dwNeeded,&dwReturned);
hdc=CreateDC(NULL,pinfo4->pPrinterName,NULL,NULL);
free(pinfo4);
}
return hdc;
}

多谢老兄，但是在NT下是找的LOCAL而不是DEFAULT，如果我把网络打印机设成DEFAULT怎么办啊，请再给个办法。多谢

你把它设成PRINTER_ENUM_DEFAULT试一下
