Abstract
A printer having multiple stages of nozzles is controlled to avoid or minimize blank space between print portions when printing on roll paper. A controller in communication with the printer is configured to determine if last partial print data to be printed contains blank raster data. If so, the controller calculates the difference between a total number of rasters in the first through the last partial print data and the number of blank rasters in the last partial print data, prints the last partial print data, and controls the paper transportation mechanism to advance the roll paper only the calculated distance to eliminate excess blank space between print portions. The functionality of the controller is also embodied in a method for controlling a printer as described above.
