A system for printing an indicia on a blank medium substrate, the printing system comprising: a print mechanism operable to mark a plurality of printouts of the indicia at a target position on the blank medium substrate and to output a printed media product, the printed media product comprising a first output group of the marked printouts, and continuous with the output of the first group of printouts, at least one output group of the printouts (223, 225) marked subsequent to the first output group; a product observer operable to observe a spatial relationship between the printouts of the indicia and the target position due to print position drift, and output a print adjustment control input; and a controller operable to adjust the print mechanism in response to receiving the print adjustment control input that is directed to correct the print position drift, wherein the adjusting conforms a position at which the printouts (223, 225) are marked in the at least one subsequent output group spatially with the target position, and characterized in that: the correction of the print position drift is performed in the media movement direction; and an amount of hundreds of printouts 221, 223 are printed as the print time continues and subsequent adjusting of the position of the marking of the printout (223, 225) functions at a moment of the print time without interrupting the printing or the movement of the print products in the media movement direction. a print mechanism operable to mark a plurality of printouts of the indicia at a target position on the blank medium substrate and to output a printed media product, the printed media product comprising a first output group of the marked printouts, and continuous with the output of the first group of printouts, at least one output group of the printouts (223, 225) marked subsequent to the first output group; a product observer operable to observe a spatial relationship between the printouts of the indicia and the target position due to print position drift, and output a print adjustment control input; and a controller operable to adjust the print mechanism in response to receiving the print adjustment control input that is directed to correct the print position drift, wherein the adjusting conforms a position at which the printouts (223, 225) are marked in the at least one subsequent output group spatially with the target position, and characterized in that: the correction of the print position drift is performed in the media movement direction; and an amount of hundreds of printouts 221, 223 are printed as the print time continues and subsequent adjusting of the position of the marking of the printout (223, 225) functions at a moment of the print time without interrupting the printing or the movement of the print products in the media movement direction. the correction of the print position drift is performed in the media movement direction; and an amount of hundreds of printouts 221, 223 are printed as the print time continues and subsequent adjusting of the position of the marking of the printout (223, 225) functions at a moment of the print time without interrupting the printing or the movement of the print products in the media movement direction.
