Abstract

In a device or method to fix print images on a recording material, a printing fluid comprising a carrier fluid and chromophoric solid particles are applied to the recording material, the chromophoric solid particles being applied in a form of the print images to be fixed. Hot waste gas and infrared radiation are generated with aid of a porous burner. The infrared radiation is directed towards the recording material in a drying chamber such that the carrier fluid polymerizes or is vaporized, whereby a gaseous air/oil mixture arises in the drying chamber. The air/oil mixture is influenced with aid of the hot waste gas of the porous burner.
