An electrographic printing system in which an improved apparatus and method are used to evaporate a volatile carrier used to deposit toner particles on a printing medium from the medium, and to fix the deposited colored toner particles permanently to the medium. The apparatus includes a unique platen and electrical heaters for dissipating different amounts of electrical power in different areas of the platen. The circulation system circulates air over the platen in order to maintain the concentration of carrier vapor below a maximum safe level.
