Abstract

A printer controller is for controlling a serial dot printer. The printer prints a dot picture on a paper by reciprocally scanning a recording head in horizontal forward and backward directions. The printer controller includes a buffer memory for storing print data in a dot pattern, a print starting address register for transferring the print data from the buffer memory to the recording head, a print end address register, an address counter, a print timing register for drive controlling the recording head, and a print timing pulse generator. The printer controller corrects vertical misregistration of print in the forward and backward printing by adjusting a set value of the print starting address of the print starting address register or a set value of the print timing register.
