    (54) Printing method for bidirectional serial printer


    (57) A printing method for a bidirectional serial printer comprising a printing data buffer (1 and 2) for at least two lines, and characterized in that:
       comparing a printing end position of a predetermined line, a left end position of a printing range for a next line, and a right end position thereof, and a judgement is made which end position, the printing operation of the next line is commenced from; and in case that a printing head moving direction from said printing end position for said predetermined line to said printing start position of the next line is the same as the printing direction at said predetermined line, said printing head is continuously scanned without any interruption also after the printing operation for the predetermined line has been completed, and is moved to the printing start position of the next line.
    In particular, a scanning speed of said printing head from the printing end position of the predetermined line to the printing start position of the next line during the continuous scanning operation, may be preferably higher than a scanning speed thereof during the printing operation.
