1. A method of printing a digital image, comprising: receiving compressed image data having spatial compression, relative to corresponding uncompressed image data, in a direction of relative movement between a print medium and a printhead, the printhead having plural spaced-apart lines of nozzles to emit a same colorant, the lines orthogonal to the direction; and printing the compressed image data using a single one of the lines of nozzles to form a printed image without the spatial compression.
