Abstract
A printing apparatus for printed electronics according to the present invention may include: ejection head units which each have at least one nozzle for ejecting ink droplets to perform drop-on-demand or continuous printing; a jetting observation unit which is provided at one side of the nozzle and configured to observe the ink droplet ejected from the nozzle; a lighting unit which is provided at the other side of the nozzle and configured to provide light to the jetting observation unit; an alignment observation unit which is configured to observe an aligned state between the nozzle and a substrate; and a fluid supply unit which is configured to supply the ink to the nozzle, in which the ejection head units include a single-nozzle head unit, and a multi-nozzle head unit provided separately from the single-nozzle head unit.
