Patent ID: 8746844

Claim:
A fluid ejection apparatus, comprising: a nozzle layer having a nozzle face, the nozzle face having a length direction along a long edge of the nozzle face and a width direction along a short edge of the nozzle face; nozzles arranged in columns, each column of nozzles oriented in a column direction substantially parallel with other columns of nozzles, the nozzles being configured to deposit droplets onto a medium that is in a relative motion with respect to the apparatus along a motion direction perpendicular to a width direction of the medium; and a first pair of directly adjacent columns and a second pair of directly adjacent columns, the first pair and the second pair being directly adjacent to each other, the nozzles of different columns of the first pair of directly adjacent columns having an offset equal to zero along the motion direction, any of the nozzles of the first pair of directly adjacent columns having a non-zero offset along the motion direction from any of the nozzles of the second pair of directly adjacent columns.
