PRINTER DRIVE SIGNAL CONTROL

摘要

A printer 100 comprises a printhead 101 comprising a plurality of nozzles 103. An input module 105 receives print data containing a specific print pattern corresponding to an image to be printed. A processor module 107 analyses the print data to predict the temperature at a first thermal region of the printhead, the predicted temperature based on a portion of the print data corresponding to a first printing fluid to be dispensed in the first thermal region of the printhead. The processor module 107 controls a first drive signal to fire nozzles in the first thermal region based on the predicted temperature for that first thermal region. A temperature sensor 111 may be provided to sense the temperature of a second thermal regional of the printhead, and wherein the processor module controls a second drive signal to fire nozzles in the second thermal region based on a temperature signal received from the thermal sensor.
