Is the word pintor the same in Brazilian and European Portuguese?

Yes

The meaning, spelling, and grammatical function of "pintor" are identical in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the vowels are generally more open and the rhythm is more melodic. In Continental Portuguese, the unstressed vowels are more closed or "swallowed," and the pronunciation of the nasal "n" before the "t" is more subtle.
