Abstract
There is provided with a printing apparatus. An ink tank stores ink to be supplied to a printhead configured to eject ink. An ink supply path supplies ink from the ink tank to the printhead. A conveying unit conveys a print medium to the printhead. A cover member is arranged so as to be able to open and close with respect to the printing apparatus. A manual valve is arranged in a region through which the print medium conveyed by the conveying unit passes and can be switched between an opening state in which the ink tank and the printhead communicate and a closing state. An operating portion is arranged at a position which is exposed when the cover member is opened and can be operated to switch the manual valve.
