Abstract
A method of compensating for bi-directional alignment error in a printing system including a carriage, a print head disposed thereon, and a bi-directional printing mode includes determining a data set by a data set determination module corresponding to bi-directional alignment error at a plurality of carriage speeds. The method also includes determining a line of best fit of the data set by a best fit determination module and identifying a flight time of fluid ejected from the print head and a carriage position error of the carriage from the line of best fit by an alignment parameter identification module. The method also includes compensating for the bi-directional alignment error by an error compensation module based on the flight time and the carriage position error.
