In one embodiment, a print bar includes: a substrate having a longer part and a shorter part extending along and parallel to the longer part such that each end of the longer part extends past each end of the shorter part; and multiple printhead dies on the longer part of the substrate. In another embodiment, a modular print bar includes a first module including multiple printhead dies joined together end to end and a second module including multiple printhead dies joined together end to end. The second module is lapped together end to end with the first module.
