ABSTRACT:
A method for controlling the print heads of an ink-jet printer includes the steps of: setting a printing direction and a print head type; loading printing data; removing odd and even data bits from the loaded printing data; determining the set printing direction; transmitting odd data and then even data and latching the transmitted odd data and then latching the transmitted even data, when the determined printing direction is a first direction; transmitting the odd data and then the even data and latching the transmitted odd data and then latching the transmitted even data, when the determined printing direction is a second direction; storing the first-latched data when the head type is monochrome; storing the second-latched data when the head type is color; and generating print data according to the stored data. A circuit for achieving the method is also provided.
