可以使用DocumentProperties函数
long lRet = 0;
lRet = DocumentProperties(NULL, hPrinter, printer, NULL, NULL, 0);
pDevMode = (PDEVMODE) new BYTE[lRet];
lRet = ::DocumentProperties(NULL, hPrinter ,printer,
pDevMode, pDevMode, DM_OUT_BUFFER );
//设置打印属性 横向或纵向 (DMORIENT_PORTRAIT)
pDevMode->dmOrientation = DMORIENT_LANDSCAPE ;
lRet = ::DocumentProperties(NULL, hPrinter, printer,
pDevMode,pDevMode, DM_IN_BUFFER|DM_OUT_BUFFER );
//构造打印dc
HDC hdcPrinter = ::CreateDC("WINSPOOL", printer ,NULL, pDevMode);
...
然后使用hdcPrinter进行打印
long lRet = 0;
lRet = DocumentProperties(NULL, hPrinter, printer, NULL, NULL, 0);
pDevMode = (PDEVMODE) new BYTE[lRet];
lRet = ::DocumentProperties(NULL, hPrinter ,printer,
pDevMode, pDevMode, DM_OUT_BUFFER );
//设置打印属性 横向或纵向 (DMORIENT_PORTRAIT)
pDevMode->dmOrientation = DMORIENT_LANDSCAPE ;
lRet = ::DocumentProperties(NULL, hPrinter, printer,
pDevMode,pDevMode, DM_IN_BUFFER|DM_OUT_BUFFER );
//构造打印dc
HDC hdcPrinter = ::CreateDC("WINSPOOL", printer ,NULL, pDevMode);
...
然后使用hdcPrinter进行打印
