A printer with reduced required space for printbar substrates in a printhead
is
disclosed. A first printbar has of a plurality of first die modules, for applying
a first color, spaced apart so as to have gaps between each die module and located
on a top surface of a first substrate. A second printbar has of a plurality of
second die modules, for applying a second color, different for the first color,
spaced apart so as to have gaps between each die module and located on a bottom
surface of the first substrate. A third printbar for applying the first color and
a fourth printbar for applying the second color, both have die modules, spaced
apart on a top surface and a bottom surface of a second substrate, that correspond
with the gaps on the top surface and the bottom surface of the first substrate, respectively.
