Zusammenfassung:	Provided in the present invention are a printing apparatus and method for an LED dam of a display panel. The apparatus comprises: a motion control system, which is used for controlling printing of a target LED dam on the upper surface of a target substrate at a target working station; a suction device, which is used for making the lower surface of the target substate sucked to a suction cup by means of a vacuum pump; a measurement system, which comprises a sensor and a sensor controller, the sensor being used for measuring flatness data of the target substrate; a Z-axis controller, which is used for controlling printing receiving distances between a target multi-printhead module and the upper surface of the target substrate; a target multi-printhead module which comprises printheads and a fluid control system, the fluid control system being used for providing a preset air pressure parameter for the printheads; and a target working station, which is used for accommodating the target substrate, so that the targ
