Abstract
A printing device is provided for printing a substance on a target surface of a target. The printing device comprises a carrier having at a first main side a hydrophobic coating for carrying a specimen of the substance to be printed, the specimen resting with a contact surface on the coating. The printing device further comprises a heater facility to locally heat the specimen at its contact surface to vaporize a portion of the specimen at the side of its contact surface and inducing a vapor pressure that causes a transfer of a remainder of the specimen towards the target surface. Additionally a printing method is provided.

A printing device for printing a substance on a target surface of a target, the printing device comprising:
- a carrier having at a first main side a hydrophobic coating for carrying a specimen of the substance to be printed, the specimen resting with a contact surface on the coating;
- and
- a heater facility configured to locally heat the specimen at a contact surface to vaporize a portion of the specimen at the side of its contact surface, to therewith induce a vapor pressure that causes a transfer of a remainder of the specimen towards the target surface.
A method of printing a substance on a target surface of a target, the method comprising:
- providing a carrier at a first main side with a hydrophobic coating;
- depositing specimen of the substance to be printed on the hydrophobic coating, the specimen resting with a contact surface on the coating;
- and
- locally heating the specimen at a contact surface to vaporize a portion of the specimen at the side of its contact surface, therewith inducing a vapor pressure that causes a transfer of a remainder of the specimen towards the target surface.
