Vertical factor parade method for both direction printer using DC motor

摘要

The present invention is based on the two sensing and comprising means, and using the DC motor to the conveying means, the print head is generated by the sensing means detection signal of the print head for recognizing the position of the print head on both sides of the printing section It relates to the vertical printing alignment method in the bi-directional printing method for performing printing operation the printer in particular, by sensing the position of the print head in the first sensing means during the transfer of the print head in the forward direction for the printing position control according to the printing operation wherein the DC conventional one-way printing method of generating a motor drive signal after the printing operation to the forward direction at the time of return operation of the spring emitter head for the printing operation in the rear direction that is transferred to the rear word direction of the printer head in the second sensing means by detecting the position of a direct current so as to accept the print control word to the rear direction Provide vertical alignment of the bi-directional printing method and a printer using the motor may perform a sort of vertical factor with an increase in effectiveness of the printing speed in accordance with the two-way printing method, but uses a DC motor.
