1. A printing device, comprising:
a solution tank; a nozzle unit including a distribution path connected to the solution tank through a first pipe, the nozzle unit including a plurality of nozzles connected to a lower surface of the distribution path; a gas supply connected to the nozzle unit through a second pipe; and a discharge unit connected to the nozzle unit through a third pipe, wherein the distribution path comprises a central portion corresponding to a plurality of first portions and a plurality of second portions alternately arranged and lateral end portions arranged at opposite ends respectively of the central portion while being adjacent to and connected to the second and third pipes respectively, wherein the first and second portions respectively have different distribution path widths due to differences in a profile of the lower surface of the distribution path at locations corresponding to the second portions between the first portions as compared to a profile of portions of the lower surface of the distribution path at locations corresponding to the lateral ends of the distribution path.
