Getting printer list on MAC OSX Topic is solved

[cutecode]

How to get a list of installed printers on MAC?

[doublemax]

I'm not 100% sure, but i think there is no API for that in wxWidgets.

http://trac.wxwidgets.org/ticket/12879

[cutecode]

this ticket is still in opened state.

I know. I just posted it as an indicator that this might not be possible.

As the ticket hasn't been touched for 4 years, it probably has been forgotten. The link to the code by one of the commenters is dead, too.

doesnt mac use cups?
if it does then cups_dest_t and cupsGetDests should get you where you need to go

eg to get the default printer

Code: Select all

cups_dest_t* dests;
	int num_dests = cupsGetDests(&dests);
	wxString retval = "";

	for (int i = 0; i < num_dests; i++) {
		if (dests[i].is_default) {
			if (dests[i].instance) {
				retval = wxString::Format("%s%s", dests[i].name, dests[i].instance);
			}
			else {
				retval = wxString::Format("%s", dests[i].name);
			}
		}
	}

	//free memory from cups data
	cupsFreeDests(num_dests, dests);

	return retval;

Thanks for a hint.
I think this code should work under Linux and MAC, since I see printer list on both OSs by following this adress http://127.0.0.1:631/printers
I downloaded cups folder with include files, but cannot figure out which lib to include into project.
Could you help me?

gotcha...

/usr/lib/libcups.dylib for MAC
and
/usr/lib/x86_64-linux-gnu/libcups.so.2 for UBUNTU

the code works as I wanted

Thank you

[cutecode]

That's my code

Code: Select all

bool GetPrinterList(wxArrayString &ar, wxString &szDefaultPrinterName)
{
    ar.Empty();
    szDefaultPrinterName.Empty();

#ifdef __WXMSW__
	DWORD dwSize, dwPrinters;
	BYTE *pBuffer;

	DWORD szz = 255;
	WCHAR c[256];
	GetDefaultPrinter(&c[0], &szz);
	szDefaultPrinterName = c;

	::EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 5, NULL, 0, &dwSize, &dwPrinters);
	if (GetLastError() != ERROR_INSUFFICIENT_BUFFER || dwSize == 0)
		return false;
	pBuffer = new BYTE[dwSize];;
	::EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 5, pBuffer, dwSize, &dwSize, &dwPrinters);
	if (dwPrinters != 0)
	{
		PRINTER_INFO_5 *pPrnInfo = (PRINTER_INFO_5 *)pBuffer;
		for (UINT i = 0; i < dwPrinters; i++)
		{
			ar.Add(pPrnInfo->pPrinterName);
			pPrnInfo++;
		}
	}
	if (pBuffer)
	{
		delete[] pBuffer;
		pBuffer = NULL;
	}

	return true;
#else
//#if defined( __WXOSX__) || defined( __WXGTK__)
    cups_dest_t* dests;
    int num_dests = cupsGetDests(&dests);

    for (int i = 0; i < num_dests; i++)
    {
        wxString sz;

        if (dests[i].instance)
            sz = wxString::Format("%s%s", dests[i].name, dests[i].instance);
        else
            sz = wxString::Format("%s", dests[i].name);

        if (dests[i].is_default)
            szDefaultPrinterName = sz;

       ar.Add(sz);
    }

   //free memory from cups data
   cupsFreeDests(num_dests, dests);

   if(ar.GetCount())
        return true;
        
      //do some other methods  
#endif
