Abstract

A printer comprising a temperature control (A) that sets a recording medium (10) conducted through the printer under motor drive approximately uniformly to a predetermined temperature, comprising a thermal writer (B) that generates a latent character image on the recording medium (10) by local heat application controlled character-dependent, and comprising a developer (C) in which the latent character image is developed by condensation of a color vapor or by color application.
