In a printing apparatus, a recording material ejection nozzle is configured to eject a holographic recording material in dots onto a support, and a hologram recording optical system is configured to emit a plurality of beams of laser light simultaneously onto the holographic recording material ejected on the support by the recording material ejection nozzle to record interference fringes therein. A scanning drive unit is configured to move the recording material ejection nozzle and the hologram recording optical system relative to the support.
