  • Modification Example 1 is an example of the printing apparatus and printing method according to the present invention, and the present invention is not limited thereto.
  • the liquid applier 20 is controlled to stop applying the liquid when the conveyance of the textile T by the conveyer 10 is stopped in the embodiment described above, such control is merely an example.
  • the liquid applier 20 may be controlled such that a small amount of liquid (per unit time) is applied as compared with that during the conveyance of the textile T by the conveyer 10, without completely stopping the application of the liquid during the stop of the textile T.
  • the liquid applier 20 may be controlled to reduce the amount of liquid applied (per unit time) in accordance with the time length of printing performed by the printer 40 during the stop of the conveyance of the textile T by the conveyer 10.
  • an absorber e.g., an absorbing roller that, when the textile T is pressed by the presser 30, absorbs the liquid attached to the presser 30 may be provided. This makes it possible to prevent the liquid from being excessively applied to the edge Te of the textile T, and also to prevent the liquid from being applied to a region other than the edge Te of the textile T.
  • the controller 100 may adjust the amount of the liquid applied per unit time by the liquid applier 20 according to the conveyance speed of the conveyer 10.
  • the ordinary tap water is mentioned as an example of the liquid applied by the liquid applier 20, but for example, a liquid having a higher viscosity than the ordinary tap water, such as a surfactant aqueous solution, may be applied.
