Because you're printing your text in the same position always. You call the putText function several times within the loops, but the text is always placed at Point(45, 180), so it overlaps from call to call (in fact not just the numbers but all the string, though as the text is always the same you don't notice it). What are you trying to achieve?

I'm guessing you're trying to get this:

for (int i=0; i < 4; i++){         
  for(int j=0; j < 3; j++){
    k++;
    Mat temp_small_image = small_image.clone();
    putText(temp_small_image, print_name(k), Point(45, 180), 
   FONT_HERSHEY_SCRIPT_SIMPLEX, 1, Scalar::all(255), 1,CV_AA);
    temp_small_image.copyTo(im_out(Rect(i*200,j*200,
   small_image.cols,small_image.rows)));
  }
}
