Abstract
For an inkjet printing apparatus having a large number of ink ejectors, it is desirable to have as few as possible interconnections to the ink ejectors. Sharing electrical ground returns between related ink ejector primitive groups with spaced apart terminals provides a reduction in interconnections while offering redundancy in the interconnection.
