Abstract
A printing device has a plurality of print stations including dot-forming elements arranged to produce an image on a moving recording medium and provided in a redundant manner, thereby enabling dot-forming-element activity to be distributed between redundant dot-forming elements and errors of dot-forming elements to be compensated. A lateral-position detector arrangement or predictor is arranged to indicate the recording medium's lateral position relative to the print stations during a print process. A controller is arranged to use at least one print mask for each print station to distribute the dot-forming-element activity between the print stations and to compensate the errors of dot-forming elements. The printing device is arranged so that, in response to a detected or predicted change of the relative lateral position, at least one of the currently used print masks is replaced by another one relating to the changed relative lateral position.
