Abstract
A method of preparing a two-dimensional bit-mapped image is disclosed in which the image has n pixels per row for printing using one or more printheads each having a row of ejection locations. Each ejection location has associated ejection electrodes to which a voltage is applied sufficient to cause particulate agglomerations to be formed from within a body of printing fluid. In order to cause charged particulate agglomerations to be ejected as printed droplets from selected ejection locations, voltage pulses of predetermined amplitude and duration, as determined by the respective bit values of the individual pixels of rows of the image, are applied to the electrodes of the selected ejection locations.
