In a printing apparatus (1), a recording material ejection nozzle (12) is configured to eject a holographic recording material in dots (P) onto a support (3), and a hologram recording optical system (100) is configured to emit a plurality of beams of laser light simultaneously onto the holographic recording material (R(P)) 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. |
