Claim:
1. An apparatus comprising: a print head having a nozzle portion; a cap unit configured to form a small capping space surrounding the nozzle portion; a humidifying unit configured to provide humidified gas in a humidified space; a first channel being connected between the humidified space and a first side of the capping space; a second channel being connected between the humidified space and a second side of the capping space which is apart from the first side; a pump disposed in the first channel configured to generate a gas flow; a valve disposed in the second channel configured to close the second channel; and a control unit configured to control at least the pump and the valve such that, the valve closes and the pump operates in order to make the humidified space to be a depressurized state or a pressurized state, then the valve opens while the capping space is formed in order to release the depressurized state or the pressurized state, thereby the humidified gas in the humidified space is distributed to the capping space in a short time through the first channel or the second channel to fill the capping space with the humidified gas.
