DOUBLE-SIDED PRINTING METHOD FOR PRINTING DEVICE CAPABLE OF EASILY CONTROLLING DOUBLE-SIDED PRINTING FOR PAPER

摘要

PURPOSE: A double-sided printing method for a printing device is provided to simplify a structure for an inverting path of paper for double-sided printing. CONSTITUTION: A double-sided printing method is provided for a printing device having a single side printing path, a paper inverting part(30) for inverting paper passing through the single side printing path, and an inversion path. One side of paper conveyed through the single side printing path is printed. The printed paper is forwarded to the paper inverting part(30). The paper inverting part(30) inverts the printed paper and conveys the inverted paper to a double-sided printing path. It is determined whether or not a front end of the paper passing through the double-sided printing path passes through a predetermined position of the single side printing path.
