只用API,你是不是也用了mfc了.谢谢.

只打印一串文字.怎么写?拜托了.

//调用OnPrint()打印

HDC GetPrinterDC (void)
{
PRINTER_INFO_5 pinfo5[3] ;
DWORD dwNeeded, dwReturned ;

if(EnumPrinters (PRINTER_ENUM_DEFAULT, NULL, 5, (LPBYTE) pinfo5,
sizeof (pinfo5), &dwNeeded, &dwReturned))
return CreateDC (NULL, pinfo5[0].pPrinterName, NULL, NULL) ;
return 0 ;
}

VOID OnPrint()
{
char c[]="只打印一串文字.怎么写?拜托了.";
static DOCINFO di= { sizeof (DOCINFO), cTable, NULL } ;
HDC hdcPrn;

if (NULL == (hdcPrn = GetPrinterDC ()))
return ;

if (StartDoc (hdcPrn, &di) > 0){
if (StartPage (hdcPrn) > 0){

TextOut (hDC, 10,10, c, strlen(c));
if (EndPage (hdcPrn) > 0)
EndDoc (hdcPrn) ;

帮你精简一下，基本就这些代码，可能编不通，你自己调试
PRINTDLG pd;
pd.lStructSize = sizeof(PRINTDLG);
pd.Flags = PD_RETURNDC;
pd.hDC = NULL;
pd.hwndOwner = NULL;
pd.hInstance = NULL;
pd.nMaxPage = 1;
pd.nMinPage = 1;
pd.nFromPage = 1;
pd.nToPage = 1;
pd.nCopies = 1;
pd.hDevMode = NULL;
pd.hDevNames = NULL;

//显示打印对话框，由用户来设定纸张大小等。
if(!PrintDlg(&pd)) return FALSE;
ASSERT(pd.hDC!=NULL);

DOCINFO di;
di.cbSize = sizeof(DOCINFO);
di.lpszDocName = "ListCtrl Data Printing";
di.lpszOutput = (LPTSTR) NULL;
di.lpszDatatype = (LPTSTR) NULL;
di.fwType = 0;
StartDoc(pd.hDC, &di);
StartPage(pd.hDC);
TextOut(pd.hDC, 0，0，subitem, strlen(subitem));
EndPage(pd.hDC);
EndDoc(pd.hDC);
//打印结束
