ABSTRACT:
Methods, systems and computer readable media for identifying print errors caused by erroneous print pattern data received at the printhead of a printer. Methods, systems and computer readable media are also provided for preventing printing according to erroneous printing pattern data received at the printhead. Methods, systems and computer readable media are provided for enhancing the printing speed of a system adapted to identify or prevent printing errors. Further, methods and systems for providing delayed clocking are used for accurate clocking of a printing signal that is sent back from the printhead to the printhead controller for purposes of comparison with a locally stored set of printhead pattern data.
