Microfluidic printing head (6) of a printer (1) characterized in that the head (6) comprises a distal face (19) and: - at least a first channel called injection channel (14) for injecting a ink on a substrate (40), the injection channel (14) opening on the face (19) distal by a first orifice called the injection orifice, - at least one second channel called suction channel (15) for sucking the ink inter alia, the suction channel (15) opening on the face (19) distal by a second orifice called the suction orifice, - a groove defined on the face (19) distal and in which the orifice suction opens at least one light source (9) or optical waveguide (17) for transmitting the light emitted by a source (9) of light. |
