check if a printed is installed and set it to default

Hello. I'dont understand C++ so much. I need to check if a printer is locally installed in a PC and set it to default printer. Can you provide some example code?

Thanks in advance,
Leonel

If you are on Windows, you can check the default printer using 'GetDefaultPrinter()' (http://msdn.microsoft.com/en-us/library/windows/desktop/dd144876%28v=vs.85%29.aspx), e.g.

TCHAR acPrinter[MAX_PATH];
DWORD dwSize = MAX_PATH;

  if (GetDefaultPrinter(acPrinter,&dwSize)) {

    // check if 'acPrinter' contains the name of the printer that you need to be the default
  }

jkr, I just need to know if a printer is installed and then set that printer as default, not getting the default printer.

For the latter you can use 'SetDefaultPrinter()' (http://msdn.microsoft.com/en-us/library/windows/desktop/dd162971%28v=vs.85%29.aspx). But, I am a bit confused, since if one printer is installed, it most likely is set as the default printer. If you want to know if there is a default printer at all, the above snippet works as well, just check for 'GetDefaultPrinter()' returning FALSE.

BTW, to enumerate all installed printers, use the sample code from http://www.news2news.com/vfp/?example=146&ver=vcpp ("Using EnumPrinters function to enumerate locally installed printers"):
void EnumeratePrinters(DWORD flags)
{
    PRINTER_INFO_2* prninfo=NULL;
    DWORD needed, returned;
 
    //find required size for the buffer
    EnumPrinters(flags, NULL, 2, NULL, 0, &needed, &returned);
 
    //allocate array of PRINTER_INFO structures
    prninfo = (PRINTER_INFO_2*) GlobalAlloc(GPTR,needed);
 
    //call again
    if (!EnumPrinters(flags, NULL, 
        2, (LPBYTE) prninfo, needed, &needed, &returned))
    {
        cout << "EnumPrinters failed with error code " 
            << GetLastError() << endl;
    }
    else
    {
        cout << "Printers found: " << returned << endl << endl;
        for (int j=0; j)
        {
            cout << prninfo[j].pPrinterName << " on " 
                << prninfo[j].pPortName << endl;
            cout << "Status=" << prninfo[j].Status 
                << ", jobs=" << prninfo[j].cJobs << endl << endl;
        }
    }
 
    GlobalFree(prninfo);
}

Open in new window


The values returned in
prninfo[i].pPrinterName

Open in new window

can be used in your call to 'SetDefaultPrinter()'.
