ABSTRACT:
A method for printing in a draft mode of a serial printer includes a first printing step for printing information data in a first direction on a first line, and a second printing step for printing information data in a second direction opposite to the first direction on a second line. The second printing step includes checking the number of dots corresponding to the data to be printed, and aligning the dots to be printed corresponding to the first and second lines in a predetermined form by determining dots to be printed according to the checked number of dots. According the principles of the present invention, every other dot is skipped and printed in turns, that is, a first dot is printed and a next dot is not printed when the number of the adjacent dots is an odd number. To the contrary, when the number of the adjacent dots is an even number, a first dot is not printed and a next dot is printed. As a result, it is possible to prevent printing data from being refracted by vertically aligning or diagonally aligning the dots.
