PURPOSE: An inkjet printing apparatus is provided to facilitate a cleaning process by minimizing the dipping height of an inkjet head in a capping unit. CONSTITUTION: An inkjet printing apparatus(100) comprises a fixed holder(110), inkjet heads(120), an injection solution supply unit, and nozzle units. The bottom of the fixed holder is opened. Mounting units(110a) having hanging protrusions(110b) are formed inside the fixed holder. The inkjet heads are inserted into the mounting units of the fixed holder and have protrusions(120a) fixed to the hanging protrusions. The injection solution supply unit supplies an injection solution to the inkjet heads. The nozzle units are formed in the inner sides of the inkjet heads and exhaust the supplied injection solution to a substrate.
