ABSTRACT:
A method and apparatus for printing an image on a print medium using an ink jet print head in an apparatus having an encoder system. The method includes generating a first firing pulse for the print head and starting a timer, waiting to receive an encoder signal from the encoder system and determining whether the timer has reached a preset time limit after the encoder signal is received, generating a second firing pulse for the print head if it is determined that the timer has reached the preset time limit after the encoder signal is received, and waiting for the timer to reach the preset time limit and generating a second firing pulse for the print head when the preset time limit is reached if it is determined that the timer has not reached the preset time limit after the encoder signal is received.
