Abstract: A method of printing a receiving material using an ink jet printer provided with a print head having at least one print element, the print head being fixed on a support element, wherein the print head is heated to a working temperature higher than room temperature, moving the support element with respect to the receiving material in a main scanning direction and in a sub-scanning direction, image-wise actuation of the print element so that ink drops are ejected from the print head in the direction of the receiving material, and guaranteeing that the position that the print head occupies with respect to a fixed point on the support element during the printing of the receiving material is substantially a predetermined position.

Abstract: A method of controlling an ink jet printer including a print head movable relative to a recording medium in a main scanning direction (Y) and having a plurality of nozzles spaced apart from each other in said main scanning direction and being energized at controlled timings for expelling ink droplets onto the recording medium, wherein the method includes the steps of: measuring at least one parameter, e. g. a temperature, that is correlated to the thermal expansion of the print head, determining, for each of the nozzles, a thermally induced positional offset (&Dgr;d1 . . . &Dgr;dn) in the main scanning direction on the basis of said parameter, and compensating for the offsets of the individual nozzles by controlling the timings at which the nozzles are energized.
