Abstract
A printing apparatus includes a print head that ejects ink for printing, an ink tank from which ink is fed to the print head, a first channel provided between the print head and the ink tank to feed ink in the ink tank to the print head, a second channel through which the ink in the first channel is transferred, and a pump connected to the second channel to transfer the ink in the first channel. The pump allows air or the ink in the first channel to be discharged via the second channel.
