1. An inkjet print module comprising:
a printhead comprising first and second rows of print chips, said printhead having 180 degree rotational symmetry about a print axis parallel to a direction of droplet ejection;
a fixed printhead keying feature extending from the printhead, said printhead keying feature being rotationally asymmetric about the print axis notwithstanding the rotational symmetry of the printhead;
a cradle for removably receiving the printhead, said cradle comprising a key assembly for complementary engagement with the fixed printhead keying feature, the key assembly being selectively configurable in either one of first and second cradle configurations, wherein:
the cradle receives the printhead only in a first printhead orientation in the first cradle configuration; and
the cradle receives the printhead only in a second printhead orientation in the second cradle configuration, the second printhead orientation being rotated 180 degrees about the print axis relative to the first printhead orientation.
