In one embodiment, a method for printing includes selecting a nozzle for printing a pixel, determining a time since the nozzle was last actuated, and, if the time since the nozzle was last actuated exceeds a threshold time, then, before actuating the nozzle to print the pixel, actuating the nozzle a number of actuations corresponding to the time since the nozzle was last actuated. In addition, when a cutting blade with a blade thickness is used, and said cutting blade is moved at a speed during cutting, and fulfill the expression 25365. The first application may render a depiction of text on the display screen. The sliding correlator despreads the N bit digital signal outputted by the AD converter and outputs the resulting correlation output as a despreading signal.
