The invention provides a printing apparatus and a printing method which enable the difference in density between one side and the other side of a sheet-like recording medium after printing to be as small as possible. A printing apparatus configured to perform printing on a sheet-like recording medium into which liquid can penetrate includes: a discharge unit configured to discharge, onto one sideof the recording medium, ink and penetration liquid which promotes penetration of the ink into the other side of the recording medium; a movement unit configured to move the discharge unit and the recording medium relative to each other when the printing is performed; and an adjustment unit configured to adjust a discharge amount of the penetration liquid discharged from the discharge unit onto the recording medium on the basis of at least a relative movement speed of the discharge unit to the recording medium.
