Image forming apparatus and high-resolution printing method in a horizontal direction

摘要

An image forming apparatus and a high-resolution printing method for the image forming apparatus are disclosed. The high-resolution printing method includes the steps of receiving from a host computer a print data, calculating a divider coefficient N, a print fire position unit (PFPU), a position offset (PO) and a print position (PP), and a print fire start position (PFSP) based on the print data, detecting a position of the carriage operated by a control signal for driving the carriage, and if the carriage reaches the PP, delaying generation of an ink firing signal, and then starting a printing by generating and outputting the ink firing signal, starting from the PFSP. A high-resolution printing in the horizontal direction can be implemented by properly controlling the PP according to a desired resolution.
