An air nozzle unit is provided above the mask plate at a place on the side edge running in parallel with the moving direction of a squeegee The temperature-conditioning air is blown sidewise from the air nozzle unit towards the cream solder during the operation of printing the cream solder on the surface of a substrate through the mask plate disposed in contact therewith.
