Arrangements of interconnect circuit and fluid drop generators

A print cartridge comprising:

• a cartridge body having a lower portion and a vertical wall;
• a printhead attached to said lower portion;
• said printhead including a first outboard array of drop generators organized in a first set of primitive groups, a second outboard array of drop generators organized in a second set of primitive groups and an inboard columnar array of drop generators organized in a third set of primitive groups and a fourth set of primitive groups;
• a contact array disposed on said vertical wall including a first outboard pair of columnar arrays of contact areas having contact areas electrically connected to said first set of primitive groups, a second outboard pair of columnar arrays of contact areas having contact areas electrically connected to said second set of primitive groups and said third set of primitive groups, and an inboard pair of columnar arrays of contact areas having contact areas electrically connected to said fourth set of primitive groups;
• said pairs of columnar arrays of contact areas being side by side and occupying a region having a height in the range of about 10 to 14 millimeters and a width in the range of about 15 to 18 millimeters;
• said columnar arrays including respective lower contact areas disposed along a lower portion of said region;
• and
• wherein lower contact areas located between transversely outermost lower contact areas are further from said lower portion than said transversely outermost lower contact areas.
