hi Nagendra,

this may or may not help you. you're using a deprecated version of my 
build environment, get the current one here:

I'm using printf with no problems, just add something like:

extern "C" int _write(int file, char* ptr, int len)
{
   display.print(ptr, ptr + len);
   return len;    // or -1
}
