Printing apparatus, method for controlling printing apparatus, and storage medium

A method for controlling a printing apparatus having

• a feed unit that feeds a printing medium,
• a print unit including a first print element array of a plurality of print elements for applying a first ink onto the printing medium and a second print element array of a plurality of print elements for applying a second ink onto the printing medium,
• a fixation unit that is located downstream of the print unit in a feed direction and fixates an image printed on the printing medium, and
• a control unit, the method comprising:
• by the control unit, using the print unit to print a first image on the printing medium by applying the first ink;
• by the control unit, using the feed unit to feed the printing medium on which the first image has been printed to the fixation unit from upstream to downstream in the feed direction,
• by the control unit, using the fixation unit to fixate the first image,
• by the control unit, using the feed unit to back-feed the printing medium on which the first image has been fixated to the print unit from downstream to upstream in the feed direction, and
• by the control unit, using the print unit to print a second image on the first image by applying the second ink.

A non-transitory computer readable storage medium storing a program for causing a computer to execute a method for controlling a printing apparatus having

• a feed unit that feeds a printing medium,
• a print unit including a first print element array of a plurality of print elements for applying a first ink onto the printing medium and a second print element array of a plurality of print elements for applying a second ink onto the printing medium,
• a fixation unit that is located downstream of the print unit in a feed direction and fixates an image printed on the printing medium, and
• a control unit, the method comprising:
• by the control unit, using the print unit to print a first image on the printing medium by applying the first ink;
• by the control unit, using the feed unit to feed the printing medium on which the first image has been printed to the fixation unit from upstream to downstream in the feed direction,
• by the control unit, using the fixation unit to fixate the first image,
• by the control unit, using the feed unit to back-feed the printing medium on which the first image has been fixated to the print unit from downstream to upstream in the feed direction, and
• by the control unit, using the print unit to print a second image on the first image by applying the second ink.
