Substrate (or marking material) pre-heating is employed to facilitate fusing of the marking material with the substrate and with adjacent marking material. By heating primarily the material (18) which becomes the interface between substrate and marking material, and by minimizing the distance between the point of heat application to the substrate (or marking material) and the marking nip in a print system, the amount of time for heat energy to dissipate prior to the application of the marking material to the substrate surface is minimized, meaning that the total amount of energy required to drive the heat source can be reduced. Addressable heating may be employed to further reduce energy consumption. Furthermore, optical heating may be used to provide rapid, on-demand heating, thereby reducing warm-up time as well as reducing unutilized heat energy.
