I have already posted this but Dafont has deleted my picture before I had time to see the answers, so I re-post this. Sorry !
(I found this picture on Tumblr)

Arial  Suggeriti da SashiX 

Has been deleted because it is too fuzzy to restore. When you post a font request try to post a picture as sharp as possible. This looks like a bitmap font but as said it can not be restored to the original. Alas.

Oh, that's why. Thank you for the information, I understand now.

As I said in other post, it's Arial with ClearType (you have it on your PC already). That image was enlarged.
