Hi V.Lorz, Firstly, it's Tesseract 3.02.02, not 3.2. We may release version 3.2 someday, but not for a long time yet ;)
Doing training is not going to help you, I'm afraid. The font is quite standard, so you aren't going to be able to do a better job at training Tesseract for it than the eng.traineddata provides. Out of curiousity, why did you think that training would help you here? I ask as it's a very common misconception, but (AFAIK) our documentation doesn't imply it anywhere. You may just have to accept that the accuracy from Tesseract won't be 100%, I'm afraid. Maybe someone else here has suggestions, but the image looks alright to me, so the general advice of "more preprocessing" may not be helpful.
