a method of printing an image from image storage memory in a printer module includes the steps of a print generator unit of a printhead interface retrieving the image from the image storage memory and transforming the image to a form suitable for a printhead . a first synchronization signal is generated to advance a paper drive stepper motor then a second related synchronization signal is generated to synchronize transfer of the image to the printhead . the transformed image is transferred to the printhead for printing by the printhead on a printable media advanced by the paper drive stepper motor in a synchronous manner .
