A printing device (33) has an in-line ink jet head (37), comprising a plurality of nozzles (38) arranged side by side in front of a printing sheet (39), in turn longitudinally movable for an in-line printing of the nozzles. The head (37) is open to transversal motion with respect ot the print medium (39) associated with the longitudinal motion of the sheet (39), over an extension and with a control of the actuations of the nozzles such as to produce a masking effect of dots unprinted due to a malfunctioning of one or more nozzles and/or an increase of the equivalent printing definition.
