Printer having array of overlapping printheads

An inkjet printer comprising an array of overlapping printheads, each printhead comprising:

• a first row of butting print chips connected to a first PCB and a parallel second row of butting print chips connected to a second PCB, the first and second rows of butting print chips having 180 degree rotational symmetry,
• wherein:
• a first printhead in the array is positioned in a first orientation relative to a media path;
• a neighboring second printhead in the array is positioned in an opposite second orientation relative to the media path;
• data signals corresponding to a first color plane are distributed only via the first PCB of the first printhead;
• and
• data signals corresponding to said first color plane are distributed only via the second PCB of the second printhead;
• and wherein each printhead comprises four ink channels for CMYK printing via the first and second butting rows of print chips, each ink channel extending between a respective inlet port and outlet port positioned at opposites ends of the printhead.
