Abstract: A printing device includes a printing head with nozzles, a movement mechanism that moves the printing head, and at least one processor. The processor controls the printing head to eject ink from each of the nozzles and to print on each position in a printing target area while causing the movement mechanism to move the printing head; and upon superposing printings in the printing target area based on pieces of data that are different from each other, controls the printing head to eject ink from at least one of the nozzles in each printing onto a different position from a position in a previous printing based on a different piece of data among the pieces of data for each of the superposing printings. The pieces of data is used in specifying from which of the nozzles ink is ejected onto each position in a printable area of the printing device.

Abstract: Examples associated with drop velocity aberrancy detection are disclosed. One example includes firing ink through nozzles of a print-head past sensors to identify drop velocities of the nozzles. A target drop velocity is selected based on the drop velocities of the nozzles. An aberrant nozzles is detected when a nozzle has a drop velocity that deviates from the target drop velocity by a selected threshold. The aberrant nozzle is deactivated, and a good nozzle that will travel over locations traversed by the aberrant nozzle is configured to print portions of a job that would have been printed by the aberrant nozzle.
