1. A handheld printer to be manipulated back and forth over a media during use to print an image on the media, comprising: a hand maneuverable housing; an inkjet printhead on or in the housing to print the image; a controller communicating with the printhead to cause printing or not; a position sensor communicating with the controller to provide a location of the housing during use, an output of the position sensor providing a plurality of pixels in a matrix frame indicating a current position frame and over time a previous position frame, wherein the controller stores a prior movement history of the printhead and based upon the prior movement history identifies a possible search area within the current position frame to compare the current position frame to the previous position frame to ascertain relative location of the printhead to the image in the possible search area, the controller including a reducer component to reduce a relative size of the output of the position sensor.
