1. An inkjet printing apparatus comprising:
a head unit including a print head provided with an ejection opening surface, the print head being configured to perform a print operation by ejecting ink in an ejecting direction to a print medium;
a platen unit including a platen having a support surface to support the print medium opposite to the ejection opening surface in a state in which the print head performs the print operation;
a cap member configured to cap the ejection opening surface;
a cap moving unit configured to move the cap member between (a) a capping position, in which the cap member is capable of capping the ejection opening surface, and (b) a separating position, in which the cap member is moved from the capping position in an opposite direction to the ejection opening surface; and
a spacer member configured to define a print gap, suitable for the print operation, between the ejection opening surface and the support surface of the platen in the ejecting direction by abutting against the head unit,
wherein the spacer member is moved to define the print gap while the cap moving unit moves the cap member to the separating position.
