A microfluidic print head of a printer has a distal face, an injection channel, a suction channel, a groove, and a light source or an optical waveguide. The injection channel is configured to inject an ink onto a substrate and leads onto the distal face by an injection opening The suction channel is configured to suck up the ink and leads onto the distal face by a suction opening. The groove is defined on the distal face and into which the suction opening leads.
