1. An end effector for printing ink on a surface, the end effector comprising:
a primary block comprising:
a primary-block body;
a plurality of primary-printing modules coupled to the primary-block body so that each one of the plurality of primary-printing modules is translationally movable, parallel to a z-axis and relative to the primary-block body; and
first actuators, each coupled to a corresponding one of the plurality of primary-printing modules and operable to selectively extend and retract the corresponding one of the plurality of primary-printing modules, parallel to the z-axis and relative to the primary-block body,
wherein each one of the plurality of primary-printing modules comprises:
at least one primary printhead;
a second actuator configured to rotate the at least one primary printhead, relative to the primary-block body, about a first axis that is parallel to or collinear with an x-axis, which is perpendicular to the z-axis; and
a third actuator configured to rotate the at least one primary printhead, relative to the primary-block body, about a second axis that is parallel to or collinear with a y-axis, which is perpendicular to the x-axis and the z-axis.
