Ink jet printing

A printing system, comprising a plurality of printheads wherein each printhead comprises a plurality of drop generators disposed in a first array and a second array, wherein:

• the first array is disposed on a first side of an ink feed slot;
• the second array is disposed on a second, and opposite, side of the ink feed slot;
• the drop generators in the first array are spaced one dot pitch apart perpendicular to a motion of a print medium, and alternate between a high drop weight (HDW) drop generator and a low drop weight (LDW) drop generator, wherein the HDW drop generators generate drops between 6 and 11 nanograms;
• the drop generators in the second array are spaced one dot pitch apart perpendicular to the motion of the print medium and alternate between an LDW drop generator and an HDW drop generator;
• and
• each drop generator in the first array is in a line of the motion of the print medium with a corresponding drop generator in the second array, wherein each HDW drop generator in the first array is in line with an LDW drop generator in the second array, and each LDW drop generator in the first array is in a line of the motion of the print medium with an HDW drop generator in the second array.
