Printing Document

[Ganesh_T]

I am facing the problem in printing document. I haev craeted the WIn32 Apllicatio and then in WM_PAINT I amdraing the ellipse. Now I want to printwhatever I see on client area. I tried with it but was giving whole scrren aftyer printing with reduced size. I need it in Win32. "A winner is not one who never fails...but the one who never quits"

Thats cause the printers resolution is more than Screens resolution heres some sample code

CDC prtDC;
CPrintInfo printInfo;
CSize size;
DOCINFO di;

CSize paper_size; //printer paper size in mm
int xLogPPI = 0;
int yLogPPI = 0;

if( AfxGetApp()->GetPrinterDeviceDefaults(&printInfo.m_pPD->m_pd) )
{
HDC hDC = printInfo.m_pPD->m_pd.hDC;
if (hDC == NULL)
hDC = printInfo.m_pPD->CreatePrinterDC();
if(hDC !=NULL)
{
prtDC.Attach(hDC);
paper_size.cx = prtDC.GetDeviceCaps(HORZSIZE);
paper_size.cy = prtDC.GetDeviceCaps(VERTSIZE);
xLogPPI = prtDC.GetDeviceCaps(LOGPIXELSX);
yLogPPI = prtDC.GetDeviceCaps(LOGPIXELSY);
}
else
{
AfxMessageBox("Can not find printer. Please check installed/default printers.");
return ;
}
}
int scr_xLogPPI = pDC->GetDeviceCaps(LOGPIXELSX);
int scr_yLogPPI = pDC->GetDeviceCaps(LOGPIXELSY);
int paper_width = (int) ((double) paper_size.cx * (double) xLogPPI / 25.4); //width of a printed page in pixels
int paper_height = (int) ((double) paper_size.cy * (double) yLogPPI / 25.4);
double ratio_x = (double) xLogPPI / (double) scr_xLogPPI;
double ratio_y = (double) yLogPPI / (double) scr_yLogPPI;

//Create GDI stuff
CFont \*pPrnFont = new CFont();
LOGFONT lf = {0};
lf.lfHeight = -14 \* ratio\_x;
lf.lfWeight = FW\_NORMAL;
\_tcscpy(lf.lfFaceName,"Times new roman");
pPrnFont->CreateFontIndirect(&lf);

..

you need to multiply everything with ratio_x and ratio_y so that everythings printed like it is diplayed on the screen Hope it Helps

I Have seen ... I need whatever is there in CLient area to be printed....I have written the sample code here: void PrintMyPage(HWND hWndMain,HDC hClientDC) { try { DOCINFO lpdi; lpdi.cbSize = sizeof( DOCINFO ); lpdi.lpszDocName = _T( "ReadMe.txt" ); lpdi.lpszOutput = NULL; lpdi.lpszDatatype = _T("RAW"); lpdi.fwType = 0; MessageBox(NULL,_T("Before CreateDC"),_T("Step by Step"),MB_OK); // CreateDC for printer //HP LaserJet 1020-rkhale@AJAY HDC hPrinterDC = CreateDC(_T("HP LaserJet 1020"),_T("HPLaserJ"),NULL,0); if(!hPrinterDC) { TCHAR szMessage[256]; wsprintf(szMessage,_T("CreateDC Failed, Last Error:%d"),GetLastError()); MessageBox(NULL,szMessage,_T("Error"),MB_OK); return; } // Lets print into the hdc if(!StartDoc(hPrinterDC, &lpdi)) { MessageBox(NULL,_T("StartDoc Failed"),_T("Error"),MB_OK); return; } // Start Page if(!StartPage(hPrinterDC)) { MessageBox(NULL,_T("StartPage Failed"),_T("Error"),MB_OK); return; } int xPage,yPage; xPage = GetDeviceCaps(hPrinterDC,HORZRES); yPage = GetDeviceCaps(hPrinterDC,VERTRES); SetMapMode (hPrinterDC, MM_ISOTROPIC) ; SetWindowExtEx (hPrinterDC, 1000, 1000, NULL) ; SetViewportExtEx (hPrinterDC, xPage / 2, -yPage / 2, NULL) ; SetViewportOrgEx (hPrinterDC, xPage / 2, yPage / 2, NULL) ; HDC hCompatibleDC; hCompatibleDC = CreateCompatibleDC(hClientDC); RECT rt; GetClientRect(hWndMain,&rt); HBITMAP hbmScreen = CreateCompatibleBitmap(hClientDC, GetDeviceCaps(hClientDC,HORZRES), GetDeviceCaps(hClientDC,VERTRES)); SelectObject(hCompatibleDC, hbmScreen); HDC tempDC = CreateCompatibleDC(NULL); SelectObject(tempDC,hbmScreen); BITMAP bmp; GetObject(hbmScreen,sizeof(bmp),&bmp); // Do BitBlt if(!::BitBlt(hPrinterDC,0,0, GetDeviceCaps(hCompatibleDC,HORZRES), GetDeviceCaps(hCompatibleDC,VERTRES),hCompatibleDC,0, 0,SRCCOPY)) { TCHAR szMessage[256]; wsprintf(szMessage,_T("BitBlt failed, Last Error:%d"),GetLastError()); MessageBox(NULL,szMessage,_T("Error"),MB_OK); return; } // Actual Printing occurs here if(!EndPage(hPrinterDC)) { MessageBox(NULL,_T("EndPage Failed"),_T("Error"),MB_OK); return; } // End Document !!! if(!EndDoc(hPrinterDC)) { MessageBox(NULL,_T("EndDoc Failed"),_T("Error"),MB_OK); return; } MessageBox(NULL

I want to use only SDK. no mfc classes. I haveposted the code in my reply to whitesky "A winner is not one who never fails...but the one who never quits" -- modified at 4:41 Tuesday 11th July, 2006

Ok Ganesh listen up, The printer resolution is far more than screen's resolution. So you need to calculate the number of times Printer resolution is greater than Screen's So get printers Resolution use

int xPrnRes = GetDeviceCaps(hPrinterDC,LOGPIXELSX);
int yPrnRes = GetDeviceCaps(hPrinterDC,LOGPIXELSY);

Get Screens Res

int xScrnRes = GetDeviceCaps(hScreenDC,LOGPIXELSX);
int yScrnRes = GetDeviceCaps(hScreenDC,LOGPIXELSY);

Get Ratio

double ratio_x = (double)xPrnRes/(double)xScrnRes;
double ratio_y = (double)yPrnRes/(double)yScrnRes;

ok so if you have an image of say 100x100 px on screen and you want to print it the destination image will be of 100*ratio_x and 100*ratio_y so instead of using BitBlt you have to use StretchBlt to stretch the Bitmap

I insert lines to this code but check your code i used PrintDlg and use from pd.hDC instead CreateDC and i cant find a ellipse in your code but when you run this code you see a ellipse almost in center void PrintMyPage(HWND hWndMain,HDC hClientDC) { try { DOCINFO lpdi; lpdi.cbSize = sizeof( DOCINFO ); lpdi.lpszDocName = _T( "ReadMe.txt" ); lpdi.lpszOutput = NULL; //lpdi.lpszDatatype = _T("RAW"); //lpdi.fwType = 0; //MessageBox(NULL,_T("Before CreateDC"),_T("Step by Step"),MB_OK); // CreateDC for printer //HP LaserJet 1020-rkhale@AJAY //HDC hPrinterDC = CreateDC(_T("HP DeskJet 1220C Printer"),"HP DeskJet 1220C Printer",NULL,0); PRINTDLG pd; memset((void *)&pd, 0,sizeof(PRINTDLG)); pd.lStructSize = sizeof(PRINTDLG); pd.hwndOwner = hWndMain; pd.Flags =PD_RETURNDC|PD_ENABLESETUPTEMPLATE; pd.hInstance = NULL; pd.nMaxPage=1; pd.nMinPage=1; pd.nCopies=1; pd.hDevMode=0; pd.nFromPage=1; pd.nToPage=1; PrintDlg(&pd); HDC hPrinterDC = pd.hDC; if(!hPrinterDC) { TCHAR szMessage[256]; wsprintf(szMessage,_T("CreateDC Failed, Last Error:%d"),GetLastError()); MessageBox(NULL,szMessage,_T("Error"),MB_OK); return; } // Lets print into the hdc if(!StartDoc(hPrinterDC, &lpdi)) { MessageBox(NULL,_T("StartDoc Failed"),_T("Error"),MB_OK); return; } // Start Page if(!StartPage(hPrinterDC)) { MessageBox(NULL,_T("StartPage Failed"),_T("Error"),MB_OK); return; } int xPage,yPage; xPage = GetDeviceCaps(pd.hDC,HORZRES); yPage = GetDeviceCaps(pd.hDC,VERTRES); SetMapMode (pd.hDC, MM_ISOTROPIC) ; SetWindowExtEx (pd.hDC, 1000, 1000, NULL) ; SetViewportExtEx (pd.hDC, xPage / 2, -yPage / 2, NULL) ; SetViewportOrgEx (pd.hDC, xPage / 2, yPage / 2, NULL) ; HDC hCompatibleDC; hCompatibleDC = CreateCompatibleDC(hClientDC); RECT rt; GetClientRect(hWndMain,&rt); HBITMAP hbmScreen = CreateCompatibleBitmap(hClientDC,GetDeviceCaps(hClientDC,HORZRES), GetDeviceCaps(hClientDC,VERTRES)); SelectObject(hCompatibleDC, hbmScreen); HDC tempDC = CreateCompatibleDC(NULL); SelectObject(tempDC,hbmScreen); BITMAP bmp; GetObject(hbmScreen,sizeof(bmp),&bmp); Ellipse(pd.hDC,100,100,400,400); // Do BitBlt /*if(!::BitBlt(pd.hDC,0,0, GetDeviceCaps(hCompatibleDC,HORZRES), GetDeviceCaps(hCompatibleDC,VERTRES),hCompatibleDC,0, 0,SRCCOPY)) { TCHAR szMessage[256]; wsprintf(szMessage,_T("BitBlt failed, Last Error:%d"),GetLastError()); MessageBox(NULL,szMess

I have the ellipse created on WM_PAINT. case WM_PAINT: hdc = BeginPaint(hWnd, &ps); // TODO: Add any drawing code here... ::Ellipse(hdc,100,100,500,500); RECT rect; rect.left = 200; rect.top = 200; rect.right = 400; rect.bottom = 400; ::DrawText(hdc,_T("I am the best"),(int)strlen(_T("I am the best")),&rect,DT_CENTER); EndPaint(hWnd, &ps); break; and on the menu click: case IDM_MENU1: hClientDC = GetDC(hWnd); PrintSelected(hWnd,hClientDC); break; I don't want directly to draw ont print dc. First I want to take the handel of my Client DC such taht whatever is drawn on the client are shouldbe printed on page "A winner is not one who never fails...but the one who never quits"
