1. A high-resolution printing method for printing in a horizontal direction for an image forming apparatus, comprising 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 print data;
detecting a position of a 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;
wherein the PO is the remainder obtained by dividing print position information by the divider coefficient N.
