The invention relates to an automatic bidirectional printing straightening system of a needle printer. The automatic bidirectional printing straightening system of the needle printer is characterizedby comprising a printing control and drive unit, a printer core unit, a grating detection sensor unit, a position collection unit and a data communication interface unit which are sequentially connected; the data communication interface unit is connected with a grating collection unit and the printing control and drive unit; and when the printing control and drive unit needs to read the position information of a current printing head in real time, a request data command is sent through the data communication interface unit, and after the position collection unit receives the request command through the data communication interface unit, the actual position, collected by a grating, of the current printing head is returned to the printing control and drive unit in real time. The automatic bidirectional printing straightening system of the needle printer achieves the bidirectional automatic straightening function of the needle printer and achieves bidirectional aligned compensation through segmented compensation.
Description
technical field [0001] The invention relates to the field of printer equipment control, in particular to an automatic two-way printing straightening system and method for a dot matrix printer. Background technique [0002] The dot matrix printer controls the printing needle to hit the ribbon through the print head, and transfers the dot matrix information to be printed to the paper through the ribbon ink. The array information is copied on the copy paper. The number of needles of the dot matrix print head is limited, generally 9 to 48 needles. To realize the printing of a complete character dot matrix or bitmap dot matrix, it is necessary to control the horizontal movement of the print head and the longitudinal movement of the paper, and print when the printing paper stops. The first horizontal movement realizes the printing of one line of dot matrix content, and then drives the printing paper to move, and then performs horizontal printing head movement printing, and the cy...
