A method is provided for depositing droplets of fluid onto a medium utilising a droplet deposition head. The method comprises, for an actuation cycle, the steps of receiving input data assigning, based on said input data, all the fluid chambers within an array of fluid chambers as either firing chambers (1)-(5) or non-firing chambers (0), (6) so as to produce bands of one or more contiguous firing chambers separated by bands of one or more contiguous non-firing chambers. The walls of the chambers are actuated such that for each non-firing chamber, if the non-firing chamber is adjacent to a band of firing chambers, one wall is actuated in the first direction while the other wall remains in the neutral position, if the non-firing chamber is a single non-firing chamber between bands of firing chambers, both walls are actuated concurrently in the first direction, and if the non-firing chamber is not adjacent to a band of firing chambers, both walls either remain in the neutral position, or are actuated concurrently in the first direction, or are actuated concurrently in the second direction. For each firing chamber, each of the first and second walls are actuated consecutively in the first direction.
