方法を提供する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for correcting print positions during printing processing on pre-printed paper by a printer such as a serial printer. When character data is printed on pre-printed paper, slips, etc. on which cross-line lines have been printed in advance, a misalignment between the cross-line position and the printing position is likely to occur depending on the paper. The present invention provides a printing position correction method for printing on such pre-printed paper with no printing deviation.

1 detects a match between the count value C of the counter 10 and △Y+△A, it determines that the printing position of the first marked line is directly below the print head 2, and outputs a printing start control signal. . By the way, the printing accuracy of paper and slips on which formats such as contour lines are pre-printed generally varies depending on the printing manufacturer and production lot, and the current situation is that it cannot be made too strict due to cost considerations. Therefore, the appropriate cueing distance △Y that is preset as a standard value
Errors between the starting distance △Y' on the actual paper and the printed characters overlap the marked line, making it difficult to see and causing print quality problems. Minor adjustments had to be made.
